Bozhko V. Analysis and synthesis of permanent magnets synchronous motors optimal control systems

Object of research are electromechanical, electromagnetic and energy processes in the electric drive systems based on permanent magnets synchronous motors (PMSM). The goal - to improve the energy performance of the electric drive system based on permanent magnets synchronous motor. Methods: methods of optimal control theory for the development of control algorithms, methods of control theory and coordinate transformations for the synthesis of improved vector control system, method of mathematical modeling for the analysis of control systems on mathematical models, experimental studies to test the adequacy of mathematical models and the results obtained by analytical methods. Novelty: permanent magnet synchronous motors vector control system was improved through allocation and control of the torque-generating parts of the stator current, thus improving the energy efficiency of the drive system; optimal control methods of permanent magnet synchronous motors "Maximum torque per ampere", "Maximum torque per volt" and "Loss minimization" were further developed by obtaining analytical expressions which take core losses into account; generalized analytic relationship between torque-generating parts of the stator current was obtained for the first time and was used for the optimal control of permanent magnet synchronous motors. The research results can be used by engineering companies and research-based enterprises engaged in development of electric drives based on electric permanent magnet synchronous motors, as well as in the educational process. The application branch is electrical engeneering.
