Research and Simulation of PMSM based on Coordination Control Technology

This paper proposed an improved stator current control algorithm of Permanent Magnet Synchronous Motor (PMSM) for efficiency optimization. According to the formula of maximum input power of PMSM, relational expression between d, q axis current is established. Appling multiple input and multiple output system coordinated control theory to current control system; the improved stator current control algorithm is given. The simulation results have proven that the algorithm proposed in this paper can maximization output power in the case of minimum coordination deviation.
