“…By using a high cost permanent magnet or separately excited synchronous ma chines, the efficiency can reach up to 95 % or more, which is purpose. The main contribution of the current paper is to verify and validate experimentally the ideas initially presented in [5,6] for the closedcycle operation of fieldorientation in duction machine drive considering the influence of a variable main inductance. Recently, more and more mechanisms that are constantly operating in dynamic mode with variable speed and variable, often unknown beforehand load.…”

Purpose. To present a comprehensive analysis of domestic and foreign experience regarding the existing optimization tech niques in the problems of the power losses minimization in electromechanical systems with an induction machine for reduction of the total electricity consumed from the grid.Methodology. A detailed study of the developments in the field of efficiency optimization of threephase induction machines through optimal control and design techniques has been done. Special attention is given to vectorcontrolled systems. Sustainable development of a few trends was traced in this domain. The reference value of the fieldgenerating current is an additional degree of freedom in the mathematical model of the investigated system. It influences the magnetic flux linkage dynamics and mechanical torque equations. Hence, the implemented model allows for a comparative analysis of different approaches to ensure minimum energy consumption with an adequate intensity of transients.findings. Among numerous control techniques, simple state control, loss modelbased control and search control efficiency optimization algorithms have been highlighted. The simulation example on efficiency optimization of an asynchronous machine was performed in the framework of an indirect fieldoriented control system considering the stepped trajectory of load torque, which is possible as a result of mechanical perturbation or when the motor performs complex speed profiles or counteracts shock loads.originality. The rigorous review indicates that existing optimization algorithms in conventional still can be used for induction motor drive applications. However, some existing problems in achieving the best control were not summarized. Accordingly, for the first time, this review provides suggestions for the future research and development of dynamic energyefficient control in in duction motors.Practical value. The threephase induction motor drives are a nonlinear system that is tough to describe precisely theoretically due to their sudden changes in conditions of operation mode and parameter variation. Thus, advanced algorithms are needed to enhance their performance in addition to effective hardware solutions. The suggested alternative solution will hopefully lead to increased efforts toward the development of advanced control systems for future applications.

“…The current paper discusses a different approach. The motivation is to give a simple and easy implementable solution to the problem of energy consumption minimization, which is characterized by a continuity of action, converges to the optimal flux level in the steadystate and expresses a compromise approach to the problem with changing loads in dynamics as well as provide an alternative solution to model predictive control [6].…”

The current paper discusses the adaptive choice of a filter time constant for filtering the steady-state flux reference in the energy-efficient control problem of field-orientation induction machines in transient behavior when load and speed conditions are changing taking into account the effect of the main induction saturation. It is shown that by appropriately managing the flux linkage rate of change the energy losses per full operation cycle under torque changes can be significantly reduced compared to the conventional cases. The analysis for the appropriate choice of the filter time constant as a fraction of the rotor time constant is based on a numerical study and simulation results for three different induction machines with different rated powers.Statement of the problem and analysis of the recent research and publications. The induction machine is widely used in industrial applications due to its robustness and its low cost compared to permanent magnet synchronous machines. However, in part-load operation, the efficiency of the induction machine dramatically decreases when the flux is kept at the nominal level. To address this issue different strategies have been developed in the past to increase the efficiency of the induction machine in a large operation range [1], [2]. However, when the induction machine is operated under changing loads these methods will not yield maximum efficiency. A solution to this problem in the framework of vehicle applications is given in [3]. However, the motor for these applications will often operate in dynamics with changing torques and speed up to voltage and current limits. The development of parametrized prototypes is discussed in [4]. Unfortunately, without voltage and current limits as well. These limits require the knowledge of the behavior of the process quantities, which can be obtained from offline optimization [5]. �� Diachenko G.G., Aziukovskyi O.O., 2020� «Системні технології» 5 (130) 2020 «System technologies» ISSN 1562-9945 (Print) ISSN 2707-7977 (Online)
