Modeling and Simulation of Direct Torque Control System on Asynchronous Motor

为了验证异步电动机直接转矩控制系统的可行性和有效性,根据直接转矩控制原理,利用MATLAB/SIMULINK软件,对异步电动机直接转矩控制系统以及系统中的异步电动机模型、磁链、转矩观测调节器模型和逆变器输出子系统模型进行了建模与仿真.仿真结果表明,直接转矩控制系统的建模与仿真具有良好的静动态性能,为直接转矩控制的进一步研究提供了依据.

To demonstrate the validity of the asynchronous motor direct torque control system, the simulation model of DTC for asynchronous motor, including the models of asynchronous motor, flux and torque estimate and regulate , and the inverter subsystem based on Matlab/Simulink is developed according to the theory of Direct Torque Control （DTC）. Simulation results show that the models developed in this paper have excellent static and dynamic performance.
