摘　　要：针对现代工业发展复杂工程下交流电机带负载能力弱、响应速度慢等调速性能差的问题,从异步电动机的数学模型入手,依据直接转矩控制和矢量控制的工作原理,基于模块化设计思想,利用Matlab/Simulink平台实现了按转子磁场定向系统的仿真建模,分析了系统模型的各组成模块,并根据两种模型得出了相应的仿真波形。实验结果表明,两种控制方式均能获得比较高的动、静态性能,而直接转矩系统在接入负载时有更好的瞬时转矩特性。Aiming at the problems of AC motor with weak load capacity and slow response speed under complex engineering of modern industrial development,starting from the mathematical model of asynchronous motor,according to the working principle of direct torque control and vector control,based on the modular design idea,using Matlab/Simulink plaform to achieve the simulation modeling according to the rotor magnetic field orientation system,The modeling process and parameter setting of each module in each system are analyzed in detail,and the corresponding simulation waveform is obtained.The experimental results show that the two control methods can obtain relatively high dynamic and static performance,and the direct torque has better instantaneous torque characteristics when connected to the load.
