基于特征模型和跟踪微分器的主动磁轴承自适应控制方法
Adaptive Control Method of AMB Based on Characteristic Model and Tracking Differentiator
摘要
Abstract
In order to improve the robustness of AMB systems in the face of noise interference and external shocks,an adaptive control method was proposed based on characteristic model and tracking differentiator.The characteristic model parameters of AMB systems were identified online through the input and output data of the control system,and the golden section adaptive controller was designed based on the identified characteristic model.The range of characteristic parameters of AMB systems was derived,the projection gradient method with nonlinear saturation function was used to identify the parameters of the systems,and the tracking differentiator was used to track and filter the meas-urement data of the control system,which further improved the robustness of AMB systems in the face of noise interference.The proposed control method was tested on the test platform of high-speed magnetic levitation motor.The experimental results show that the tracking differentiator may effec-tively filter out the interference of external noises on the measured data.Compared with the commonly used incomplete differential PID control method,the proposed adaptive control method may effective-ly improve the control accuracy and robustness of AMB systems,and the vibration peak values of the magnetic suspension rotor are reduced by 51.4％.关键词
