Simulation of PMSM DTC System Based on zero-vector and Fuzzy PI Speed Controller

摘要

In order to improve the dynamic performance of direct torque control (DTC) permanent magnet synchronous motor (PMSM) system, a DTC strategy with zero-vector and fuzzy PI speed controller is proposed in this paper. Based on Matlab/Simulink, the simulations models of the proposed DTC PMSM system and traditional DTC PMSM system are established. Simulation results show that the proposed control strategy has fast response and small ripple, which verify correctness and feasibility of the proposed DTC system.
