Deadbeat Predictive Current Control for Permanent Magnet Synchronous Motor

A single beat deadbeat predictive current control (DPCC) method for permanent magnet synchronous motor (PMSM) was proposed. The motor current state equation was derived based on its model, and the regulator expression of single beat DPCC has been obtained from its model. At last, a performance comparison of this algorithm was compared with the conventional vector control and double beat DPCC algorithm. The results show that single beat DPCC has the advantages of fast dynamic response, strong resistance to load disturbance and wide response frequency band compared with the other two strategies, thus has good industrial application prospects.
