The dynamic response and anti-disturbance ability are an important index of direct torque control (DTC). Based on the mathematical model of built-in permanent magnet synchronous motor (IPMSM), a simulation method of IPMSM-DTC system is proposed. The dynamic response and anti-disturbance performance of the system are analyzed by model. Power. Using MATLAB / Simulink to build an independent sub-module, and its working principle and construction method are introduced in detail. IPMSM-DTC system simulation model is constructed through the organic combination of sub-modules.
