Simulation study on a DTC system of PMSM

Abstract

In order to improve the dynamic performance of PMSM, a Direct Torque Control (DTC) scheme of Permanent Magnet Synchronous Motor (PMSM) is presented. Based on in-depth analysis of PMSM mathematical model and the operation principle of DTC system, Matlab/Simulink is used to establish a simulation model of this system, and extensive research of simulation is conducted. A large number of simulation results show that the DTC System of PMSM has fast response and good dynamic performance, which verify correctness and feasibility of this system.
