This paper discusses open phase faults, which can happen in a system grid-converter-motor drive, and measures to properly handle this type of fault. The authors of this paper provide classification of algorithms used for the detection of the loss of phase and explain the distinctive features of each group of methods. They review existing algorithms, which are based on the analysis of the current signals, discuss their pros and cons and suggest possible areas of usage for each group of methods. The authors also propose one novel method for detection of open phase, which was developed for low-cost systems with low resolution analog-to digital converters (ADC). This paper mainly considers methods for three-phase motors as the most popular machines, however some algorithms can be used in multiphase drives. The authors of the paper also share their more than 20 years’ experience combined, in this area, which was obtained by developing industrial and commercial drives, and focus on the requirements of the IEC/UL 60730 safety standard, where the phase-loss detection algorithm is one of the essential parts of control system.

Synchronous homopolar motors (SHMs) have been attracting the attention of researchers for many decades. They are used in a variety of equipment such as aircraft and train generators, welding inverters, and as traction motors. Various mathematical models of SHMs have been proposed to deal with their complicated magnetic circuit. However, mathematical techniques for optimizing SHMs have not yet been proposed. This paper discusses various aspects of the optimal design of traction SHMs, applying the one-criterion unconstrained Nelder–Mead method. The considered motor is intended for use in a mining dump truck with a carrying capacity of 90 tons. The objective function for the SHM optimization was designed to reduce/improve the following main characteristics: total motor power loss, maximum winding current, and torque ripple. One of the difficulties in optimizing SHMs is the three-dimensional structure of their magnetic core, which usually requires the use of a three-dimensional finite element model. However, in this study, an original two-dimensional finite element model of a SHM was used; it allowed the drastic reduction in the computational burden, enabling objective optimization. As a result of optimization, the total losses in the motor decreased by up to 1.16 times and the torque ripple decreased by up to 1.34 times; the maximum armature winding current in the motor mode decreased by 8%.

The synchronous homopolar motor (SHM) has been attracting the attention of researchers for many decades. Various mathematical models of SHM have been proposed to deal with its complicated magnetic circuit. Among them, there are time-consuming 3D finite element models (FEM), equivalent circuit models neglecting some significant features of the machine design, and 2D FEM models with virtual excitation winding distorting magnetic field picture. This paper proposes a novel 2D FEM of SHM and shows that since there are no sources of excitation in the cross-sections of the rotor and stator stacks, no virtual elements are required. This model uses the general solution of the Gauss’s law for magnetism containing excitation flux. The model is based on a set of magnetostatic boundary value problems for various rotor positions. The set of boundary problems is completed with the excitation equivalent circuit. The losses in the armature and field windings and in the stator and rotor magnetic cores are computed in postprocessing. All these computations are carried out for a single combination of stator and rotor stack. A symmetrization algorithm is proposed to extend the obtained results to the whole SHM. A comparison of the theoretical and experimental data for a nine-phase three-section 320 kW SHM is carried out. These SHMs were used in a mining truck with a carrying capacity of 90 tons.

Interior permanent magnet synchronous motor (IPMSM) efficiency can be improved by using maximum torque per ampere control (MTPA). MTPA control utilizes both alignment and reluctance torques and usually requires information about the magnetization map of the electrical machine. This paper proposes an adaptive MTPA algorithm for sensorless control systems of IPMSM drives, which is applicable in industrial and commercial drives. This algorithm enhances conventional control schemes, where the output of the speed controller is the commanded stator current and the direct current is calculated using an MTPA equation; therefore, it can be easily implemented in the previously developed drives. The proposed algorithm does not use any motor parameters for the calculation of the MTPA trajectory, which is important for systems operating in changing environmental conditions, because motor inductances and flux linkage strongly depend on the stator current and the rotor temperature, respectively. The proposed algorithm continuously varies the current phase and in such a way it tries to minimize the magnitude of the stator current at the applied load torque. The main contribution of this paper is the development of a technique to overcome the main disadvantage of seeking algorithms–the necessity of a precision information about the rotor position. The proposed method was verified experimentally.

A problem of the switched reluctance drive is its natural torque pulsations, which are partially solved with finite control set model predictive control strategies. However, the continuous control set model predictive control, required for precise torque stabilization and predictable power converter behavior, needs sufficient computation resources, thus limiting its practical implementation. The proposed model predictive control strategy utilizes offline processing of the magnetization surface of the switched reluctance motor. This helps to obtain precalculated current references for each torque command and rotor angular position in the offline mode. In online mode, the model predictive control strategy implements the current commands using the magnetization surface for fast evaluation of the required voltage command for the power converter. The proposed strategy needs only two lookup table operations requiring very small computation time, making instant execution of the whole control system possible and thereby minimizing the control delay. The proposed solution was examined using a simulation model, which showed precise and rapid torque stabilization below rated speed.

Subject of Research. The paper discusses design principles of educational laboratory bench for practical research of electric drive control systems. The laboratory bench provides training opportunities for students in “Control of Electrical Drives” course and is used to increase the efficiency of material acquisition. Method. The proposed solution was based on the method of mutual loading of electric machines powered by the power converters with a common direct current link. At that, one electric machine can be used as a tested one, and the other as a load one, and vice versa. The flow of power from a machine operating in generator mode to a machine operating in motor mode was ensured, which provides an energy-saving mode of operation when power is consumed only from the network to cover losses in power converters and the machine unit. To study the various structures of control systems for direct and alternating current motors, a method for software creation with a freely configurable structure was proposed. Main Results. The paper describes laboratory stands that contain a two-machine unit, where each electric motor receives power from its power semiconductor converter controlled by a real-time microcontroller control system. The software has been implemented for the synthesis of the control researched structure using the control system settings. The system setting is performed by a number of freely configurable control elements, which are then compiled into a control algorithm for the microcontroller. To ensure the safe execution of the experiment, the control algorithm works in conjunction with the main on-line software. Thus, protection for electric motors and power converters is provided. Thanks to the built-in protection software, it has become possible to achieve reliable operation of electric drives with the power of 1.5 kW, as well as to realize characteristics close to industrial ones. The paper describes in detail the features of laboratory equipment and software for the system of an induction motor field-oriented control. This example demonstrates the setting of control systems, compiling of executable code, an experiment procedure and evaluation of results. Practical Relevance. The considered approaches to the educational equipment creation can be used in the design of similar educational equipment in related disciplines. The results are applicable for scientific and research-pedagogical staff during the course of specialist training in the field of electric drive control systems. The presented equipment has been actively used for more than 5 years and can be of practical value in the educational process.

This paper proposes a high-performance speed measurement method for variable speed electric drives using incremental encoders. It is based on the well-known constant elapse time (CET) method. However, the principle of speed estimation is changed from event driven to ready on demand. This helps to remove the jitter effect, caused by the asynchronous nature of the CET method, and make the speed estimation time constant regardless of the current speed. The proposed method can be implemented on modern motion control microcontrollers. Experimental results using a vector controlled Permanent Magnet Synchronous Motor (PMSM) are provided to confirm the performance of the proposed algorithm and the improvements with respect to conventional methods. Synchronous CET method of speed estimation allows to double the accuracy compared to the original CET method for the same behavior of the speed loop, or to increase the speed response time twice for the same accuracy.

This paper discusses a method of the current derivative measurement using a standard closed-loop Hall-effect current sensor. The proposed method can operate with PWM-driven inverters and provides the estimation of motor-phase inductances required for an encoderless or self-sensing control. The method is based on the current transformation feature of the closed-loop sensor where a sensing inductor is connected in series with the measuring resistor. The voltage drop across the inductor is proportional to the current derivative. The experimental results are demonstrated that the measurement of the current derivative can be performed under a good accuracy, though the measurement should be executed while inverter is in the steady-state condition.

The article deals with testing a combined PWM method for a voltage source inverter, which is aimed at minimizing the switching losses and distributing them among the power converter modules. To reduce switching losses in the inverter, duty cycles are calculated for several possible PWM shaping methods, and a PWM method in which the phase with the largest value of current flowing through it is not switched is chosen. Another advantage of this method is its ability to control the thermal operating conditions of the inverter’s IGBT modules. This is especially important for designs in which the power IGBT modules are installed on a common heat sink, because with such configuration, the modules of a three-phase converter operate under different thermal conditions. To avoid overheating of a particular IGBT module, an algorithm is proposed using which losses can be redistributed among the modules. Since it is difficult to establish an exact mathematical relationship between the desired behavior and the controlled parameters, a prediction method is used. The total losses anticipated for each possible PWM method are calculated, and the objective function that takes into account several variable parameters is determined. By varying the objective function’s weighting coefficients, different system operation modes can be specified. Three system operation modes defined by three objective function configurations are analyzed. In its first configuration, the objective function makes it possible to select the PWM method in which the total losses in the system are kept to a minimum. In its second configuration, the objective function allows the user to calculate the minimum losses in the inverter’s most heavily heated leg. In its third version, the objective function is a combination of the first two configurations and is aimed at simultaneously reducing the total losses in the system and losses in its most heavily heated module. The performance characteristics of each of these three objective functions and of the standard vector PWM are tested on a heat sink thermal model. The presented simulation results show that application of the first objective function helps to decrease the total losses in the system as compared with those in the case of using the standard vector PWM; application of the second objective function makes it possible to decrease losses in one phase, whereas the temperature in the other legs tends to grow; and the third objective function was found to be the most effective one, because its application made it possible to achieve the minimal losses in the system and a lower temperature of the most heavily heated module. Цель настоящей статьи — тестирование комбинированного метода широтно-импульсной модуляции (ШИМ) для инвертора напряжения, минимизирующего коммутационные потери и распределяющего их между модулями силового преобразователя. Для снижения коммутационных потерь в инверторе рассчитаны скважности для нескольких возможных способов формирования ШИМ, и выбран тот способ, в котором фаза с наибольшим значением протекающего по ней тока не коммутируется. Еще одна возможность данного метода — управление тепловым режимом IGBT-модулей инвертора. Это особенно важно в тех случаях, когда силовые IGBT-модули установлены на общем радиаторе. Для трехфазного преобразователя данная конфигурация предполагает неодинаковые термические условия для модулей. Чтобы избежать перегрева конкретного IGBT-модуля, предложен алгоритм, позволяющий перераспределять потери между модулями. Поскольку сложно установить точную математическую зависимость между желаемым поведением и управляемыми параметрами, то использован метод прогнозирования. Проведен предварительный расчет прогнозируемых общих потерь для каждого возможного способа ШИМ, определена функция цели, учитывающая несколько изменяемых параметров. Меняя весовые коэффициенты функции цели, можно задавать различные режимы работы системы. Проанализированы три режима, определяемые тремя конфигурациями функции цели. Первая функция цели позволяет выбрать тот способ ШИМ, при котором общие потери в системе минимальны. Вторая функция цели обеспечивает расчет минимальных потерь в самой нагретой стойке инвертора. Третья функция цели представляет собой сочетание первых двух и одновременно снижает общие потери системы и потери в самом нагретом модуле. Действие каждой из трех целевых функций и стандартной векторной ШИМ протестировано на тепловой модели...

Рассматривается проблема интерференции тока, потребляемого электродвигателем компрессорного агрегата вагона метро, с сигналами, используемыми системой предотвращения столкновений, на некоторых частотах. При модернизации силового преобразователя, который питает асинхронный электродвигатель компрессора, размеры входных фильтров были уменьшены для повышения надежности и снижения цены. Это привело к значительному увеличению потребления тока на частотах 275 и 325 Гц, используемых системой предотвращения столкновений. Проблема была рассмотрена и предложен способ ее решения. Способ подразумевает постоянное регулирование мощности, потребляемой электроприводом компрессора, что позволяет уменьшить гармонику тока с частотой 25 Гц, создаваемую моментом нагрузки; таким образом, пульсация 300 Гц от выпрямителя на тяговой подстанции не интерферирует с пульсацией мощности, обусловленной механикой компрессора. Поэтому гармоники тока с частотами 275 и 325 Гц снижаются и не влияют на работу системы предотвращения столкновений. Предлагаемый способ управления был реализован, представлены экспериментальные результаты.

This paper considers a PWM strategy with minimization of switching losses and their redistribution between the modules of the power converter. The strategy combines method of switching losses minimization by choosing the most efficient discontinuous PWM pattern and an active thermal control of the hottest IGBT module in the system. The algorithm predicts the total losses in the system for different PWM patterns and losses in the hottest IGBT module. The cost function takes into account both values. The provided simulation results display the decrease of maximum temperature in the system, while the total losses slightly increase.

The study discusses the design principles of instructional laboratory equipment applied for practical investigations of electric drive control. The laboratory workstations comprise of two-motor hardware systems where each motor is controlled by a real-time DSP board. A control structure under test is assembled at the software level using a number of control elements, which is then compiled into a control algorithm for the microcontroller. In order to provide safe test execution, the control algorithm operates under the supervision of a real-time core software ensuring protection of the motors and the power converters. Due to the improvement in the reliability of hardware operation, the rated power of the motors and converters is increased to >1 kW to provide a proper characterisation of electric drives similar to industrial installations. The study also describes the laboratory hardware and software details using an example of the control system for an induction motor based on flux-vector control strategy. The example demonstrates configuring the control systems, compiling it into the execution code, the test procedure and result analysis.

The parallel processing of motor control system using modern FPGAs allows the complex servo algorithms to be proceeded within a microsecond, resulting in extreme high control bandwidth. At the same time a powerful processing core is needed for the drive to be built in real-time industrial networks. A System on Chip enables to solve both of the tasks within a single chip.

The paper provides performance analysis of an induction motor drive fed by a Z-source inverter operating under random pulse width modulation. The paper also provides a description of control techniques based on a random pulse position PWM obtained using a triangular carrier waveform. The control algorithm has characteristics of both space vector and random lead-lag modulations. The random PWM signal is generated using pseudorandom binary sequence bits and the PWM pulses obtained from a comparison of two fixed frequency triangular carrier waveforms and a reference voltage. The control technique has been applied to a Matlab/Simulink model of the induction motor drive which has been simulated and analysed. The results showed that the harmonics of a Z-source inverter output are dispersed and continuously distributed across the spectrum.
