Decoupling Control and Disturbance Rejection of Radial Rotor System in Magnetically Suspended Control Moment Gyro Based on ADRC
摘要
Abstract
In order to overcome disturbance effect in stability of magnetic suspended rotor and output torque accuracy of magnetically suspended control moment gyroscope, this paper presents a disturbance rejection method of magnetic suspended rotor based on active disturbance rejection controller. The dynamics model of magnetic suspended rotor is established, decoupling model of radial four channel is obtained based on principle of ADRC, rotor radial four channel decoupling and disturbance rejection is achieved through ADRC. Through simulation, we find ADRC controller has good function of disturbance rejection, canimprove stability precision of rotor and output torque accuracy of control moment gyroscope. Therefore, this method not only improves accuracy of decoupling control, but also improves the robustness of system to external disturbances and parameter variations, and can be used in high precision strong robust control for magnetically suspended control moment gyroscope.关键词
