Speed control system of SPMSM drives with field weakening on base the concept of inverse problems of dynamics

Abstract

Speed control system of SPMSM drives with field weakening based on the concept of inverse problems of dynamics is presented in the paper. This concept allows obtaining robust algorithms for controlling the components of the stator current, and the speed of a surface permanent magnet synchronous motor (SMPMS) that had provided stability of dynamic characteristics in the conditions of changing the parameters of the control object in the proposed range. Estimating quality indicators had made by mathematical modeling of the control processes. The research results had confirmed the effectiveness of the proposed method control coordinates of synchronous drive.
