Speed Control System of Synchronous Motor Drives with Field Weakening using the Concept of Inverse Problems of Dynamics

Abstract

Speed control system of surface permanent magnet synchronous motor (SPMSM) drives with field weakening is presented. The control algorithms for electromechanical coordinates are synthesized using the concept of inverse problems of dynamics. This concept allows obtaining robust algorithms for controlling the components of the vector control system that are provided stability of dynamic characteristics in the conditions of changing the parameters of the control object in the proposed range. The quality of the automatic control system is evaluated using mathematical modeling. Effectiveness of the applied method control of electromechanical coordinates of electrical drive has confirmed research data.
