Model-predictive control (MPC) has emerged as a promising control method in power electronics, particularly for multiobjective control problems such as multilevel inverter (MLI) applications. Over the past two decades, improving the performance of MPC and tackling its technical challenges, such as computational load, modeling accuracy, cost function design, and weighting factor selection, have attracted great interest in power electronics. This article aims to discuss the current state of MPC strategies for MLI applications, describing the significance of each challenge with the reported effective solutions. Through this review, the MPC methods are categorized into two groups: direct MPC (without modulator) and indirect MPC (with modulator). The recent advances of each category are presented and analyzed, focusing on direct MPC as the most applied method for MLI topologies. In addition, some of the important concepts are experimentally validated through a case study and compared under the same operating conditions to evaluate the performance and highlight their features. Finally, the future trends of MPC for MLI applications are discussed based on the current state and reported developments.

Francesco Castelli-DezzaThis paper presents a model predictive control (MPC) algorithm for a three-level neutral point clamped converter connected to the grid via an LCL filter. The proposed long horizon MPC method, formulated as a multi-criterion quadratic program (QP), simultaneously controls the grid and converter current as well as the filter capacitor voltage, while meeting the relevant grid standards. To achieve the latter, a carrier-based pulse width modulation (CB-PWM) stage is employed. Finally, soft constraints are included to ensure operation of the system within its safe operating limits, particularly with regards to a potential overcurrent or overvoltage trip during transient operation. The presented simulation results based on a medium-voltage system as well as experimental studies based on a scaled-down prototype verify the effectiveness of the proposed method.
Journal Article
This paper proposes a model-based two-degree-of-freedom (2DOF) speed control for a medium voltage (MV) variable speed drive (VSD) connected to a centrifugal compressor (CC) train. Torsional mode excitations in the drive shaft due to converter switching behaviour are considered. An effective description of the harmonics transfer is proposed. The tuning strategy aims to optimize the tracking behaviour of the step and ramp command, taking care of critical speed excitations. The stability of the closed-loop dynamics against time delay and drive parameter variations are studied by means of Nyquist diagrams and time-domain simulations. A descriptive method for the process damping behaviour is proposed. The control strategy is evaluated through simulations as well as an experimental setup, based on a hardware in the loop (HIL) in a master–slave configuration.

Multi-level converters are a possible solution for increasing the power density and efficiency in many power electronic systems. The increase in the number of switching components on a single device leads to a growth both in the cost of the converter and in its complexity compared to two-level solutions. However, these drawbacks are counterbalanced by a better harmonic content on the AC quantities, allowing a significant decrease in the size of the output filters and reactive power as well. Thus, three-level converters represent a good compromise between costs, system complexity and efficiency. More specifically, this paper focuses on the development of a bidirectional control for a three-phase three-level T-type converter working as an active front end to be coupled with DC/DC converters in off-board recharging stations or in renewable power plants. Moreover, a thermal analysis of the power electronics is carried out aimed to the design and the development of an ad hoc cooling system for a prototype working at 80 kW.

Francesco Castelli-DezzaThe paper presents a practical solution for an existing drive-train to avoid torsional vibrations for variable speed drives under SPWM modulation technique. Torsional natural frequencies can be a problem because either ill defined in design stage or one of the mechanical parameters has changed after the initial design stage. The proposed method comprises of dividing the frequency range into several partitions where in each partition a value of modulation frequency ratio m f is chosen. A criterion is developed to choose m f based on avoiding torsional excitations with the minimum converter losses. Torque harmonic distortion and converter losses are analyzed. Matlab/Simulink is used to validate the approach.
