This paper discusses that conventional direct torque control (DTC) system of permanent magnet synchronous motor (PMSM) exists in the stator flux linkage and electromagnetic torque ripple faults, and puts forward a method using variable parameter PI controller and fuzzy controller respectively used to replace PI speed regulator and hysteresis comparator of the conventional direct torque control and constructs a new direct torque control system of permanent magnet synchronous motor. The experiment results showed that the improved system has good dynamic and static performance, less flux and torque ripple.
