摘　　要：介绍了自抗扰控制器的内部结构及其各组成部分的功能,并将自抗扰控制系统应用于在异步电动机调速系统中,此控制方案不需要精确的电机模型就可以实现干扰补偿,使得自抗扰控制器的设计能够独立于异步电动机精确的数学模型。在MATLAB/Simulink环境下进行了仿真研究,并根据仿真结果分析了线性自抗扰控制系统较传统PID控制器的优缺点。The structure and characteristics of ADRC are studied in this paper , the ADRC is applied in controller system of induction motor . The proposed strategy realizes the disturbance compensation without accurate knowledge of induction motor parameters, that means the design of ADRC is independent of the accurate induction motor model. Through simulation tool MATLAB/simulink, this paper presents results of simulation for design of linear structure of an ADRC and implement of ADRC in the vector control system. From the point of simulation, benefits and drawbacks between linear ADRC and traditional PID controller are analyzed.
