In this paper, a Fractional Order Power System controller (FOPSS) is designed, and its performance and robustness are experimentally evaluated by tests in a 10 kVA laboratory scale power system. The FOPSS design methodology is based on the tuning of an additional design variable, namely the fractional order of the controller transfer function. This design variable is tuned aiming to obtain a tradeoff between satisfactory damping of dominant oscillating mode and improved closed-loop system robustness. For controller synthesis, transfer function models were estimated from data collected at selected operating points and subsequently applied for the controller design and for obtaining upper bounds estimates on the operating-point depends on plant uncertainties. The experimental results show that the FOPPS was able to obtain a robust performance for the considered set of the power system operating conditions.

Strategic Planning is one of the management tools most used by institutions that seeks to translate the organization's strategy, define its strategic objectives, identify the main existing bottlenecks and anticipate changes. The indicators are allies of planning and fundamental to the control of processes, because they make it possible to monitor goals, correct problems and propose alternatives for solving possible problems. Therefore, this research consists of verifying the actions outlined in strategic planning in the public sector, using the balanced scorecard tool. For that, a systematic literature review was used as the methodological procedure as the main theme the use of the BSC as a strategic management tool in the public sector. Around 2.003 articles relevant to the proposed theme were identified, selected from 2015-2020, of which 11 deal directly with the use of the BSC. As a result, the survey found the concern that public organizations have been demonstrating in perfecting their strategic plans by adapting the BSC to the reality of the public sector so that they provide better services to society.

This article aims to study the application of standardization techniques in a two-wheel hub company in the city of Manaus, more specifically in the subassembly sector of the chassis, responsible for the preparation of parts to supply the assembly line. The methodologies used were the 5S methodology, which is proven very effective in identifying and eliminating waste and increasing efficiency; the standardization of intermediate stock, to improve the performance of the purchasing and business sectors, and finally, the PDCA cycle, to identify needs and find suitable, low-cost solutions. From the data collected, the problem was defined as the three worst parts, which are the mudguard, rear fork, and top cover, as it was found that they are recurrent in more than 50% of the models produced. These defects are due to the improper storage of the parts, which present scratches and beat marks. The need to establish an ideal condition of ideal storage was raised, and a manual was elaborated in which basic actions are listed to avoid small defects. After applying the mentioned tools and methodologies, the company managed to reduce the occurrence of small defects.

Value Stream Mapping (VSM) enables, through its own symbology, the improvement of the flow of materials and information, helps to eliminate activities that do not add value and other waste. The present study refers to the application of the VSM tool for the improvement of a television productive process of a company in the Manaus Industrial Pole. The research is classified as a case study with a qualitative approach, of an applied nature with an exploratory objective. Activities throughout the production process were analyzed and characterized to obtain points of improvement in operating time, such as a 75% reduction in inventory time and 7.3% in the final line. As a contribution, it was possible to identify the points of unproductive that cause losses and failures that can help for future studies and new improvements.
