Robust Vector Control of Interior Permanent Magnet Synchronous Motor with a Strategy of Maximum Torque per Ampere

Abstract

A robust system of vector control of the angular speed of the rotor of a synchronous electric drive for the first zone without field weakening is given. The strategy of maximum torque per ampere was used as the optimal control strategy. A synchronous machine with permanent magnets located in the middle of the rotor was used for the study. Control algorithms for the vector system were developed based on the concept of inverse dynamics problems. The robustness of the automatic system was checked by varying the active resistance of the stator winding of the research machine and by evaluating the quality of the transients of the electromechanical coordinates of the system. The research was carried out by the method of mathematical modeling of the vector system. The energy performance of the system was also analyzed.
