Active disturbance rejection control based on aerostatic pressure moving platform simulation analysis and experimental research
In order to further improve the stability and anti-interference performance of the aerostatic platform,the control algorithm of the aerostatic platform is studied according to the disturbance existing in the platform itself.This paper proposes an auto-disturbance rejection control algorithm combining PD control and linear extended state observer.The control model is built in Matlab/Simulink for simulation analysis,and the platform is built for experimental verification.This algorithm solves the disturbance problem of the traditional PID control algorithm in the gas static pressure moving platform.The results show that compared with the traditional PID control algorithm,the active disturbance rejection control algorithm can effectively reduce the tracking error,reduce the overshoot,and improve the anti-interference performance of the aerostatic movement platform.
