摘要
传统的感应电机直接转矩控制系统存在转矩脉动大等缺点,为提高感应电机直接转矩控制系统的动态性能,该文采用一种改进的转矩估算模型,在推导其数学模型的基础上,采用Matlab/Simulink仿真软件对感应电机新型直接转矩控制系统进行建模与仿真,仿真实验研究结果表明:采用改进的转矩估算模型可以提高异步电动机直接转矩控制系统的动态性能。
The direct torque control（DTC） system of the traditional induction motor has many disadvantages,such as the big ripple of torque.In order to improve the dynamic performance of the DTC system of the induction motor,the modeling and simulation were used in the DTC control system.By adopting the improved model of the torque estimation,the simulation model of the control system and the induction motor was established using MATLAB/SIMULINK software package.This new model of the torque estimation was constructed which can be applied to the control system.The simulation and experimental results have shown that the dynamic performance of the DTC control system for induction motor is enhanced by the improved model of the torque estimation.
