The paper introduces a kind of method about current loop control system which is based on position and velocity dual-closed loop control system. This method improves effectively the performance of velocity closed loop control system and amplifies the gain of low frequency. The results show applying these control methods  the influence of the torque ripple has decrease 50% and the compensation rate precsion has promoted double. 2011 IEEE.
