Paper Title:
Direct Torque Control of PMSM Based on Variable Parameter PI and Fuzzy Control
  Abstract

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.
