基于非线性自抗扰控制器的异步电机高性能控制

本文将非线性自抗扰控制器应用到异步电机调速系统中，由自抗扰控制器取代经典PID控制器对异步电机进行控制，提出了应用自抗扰控制器的异步电机调速系统的设计方案。通过在一台2.2 kW异步电机上进行突加负载、正反转等实验，自抗扰控制器被证明具有良好的动态性能，并且其对负载扰动、电机参数变化都具有较好的鲁棒性。

High Performance Control of Induction Motor based on Nonlinear Auto-Disturbance Rejection Controller

A new control strategy which substitute the classic PID controller to the control of induction motor is presented, that is: auto-disturbance rejection control (ADRC). To demonstrate the effectiveness of proposed scheme, the ADRC is applied to the speed control of a 2.2 kW induction motor. Simulational and experimental results show that the controller operates quite robustly under modeling uncertainty, load disturbance and parameter variation. The whole system is proved that it has robustness and high dynamic performance, such as small overshoot and fast setting time.
