摘　　要：本文简要介绍了永磁同步电机的数学模型以及永磁同步电机直接转矩控制系统基本原理,并基于Simulink仿真平台搭建了永磁同步电机直接转矩控制系统仿真模型,给出了模型各模块的搭建过程。使用该模型进行了3种不同工况下的仿真研究,通过仿真得出了直接转矩控制系统可以很好地跟踪输入的变化,具有响应速度快、抗干扰能力强的优良性能。本研究为永磁同步电机直接转矩控制系统的进一步奠定了基础,具有一定的工程指导意义。This article briefly introduces the mathematical model of permanent magnet synchronization and the basic theory of direct torque control system.Based on the Simulink simulation platform,a simulation model of direct torque control system for permanent magnet synchronous motor is built,and the construction process of each module of the model is provided.The model was used for simulation studies under three different operating conditions,and it was found that the direct torque control system can effectively track the input changes,and has excellent performance such as fast response speed and strong anti-interference ability.This study lays the foundation for the further development of direct torque control systems for permanent magnet synchronous motors and has certain engineering guidance significance.
