摘　　要：为了进一步提高气体静压运动平台的稳定性以及抗干扰性能,针对气体静压运动平台自身存在的扰动对其控制算法进行研究。文章提出了一种PD控制与线性扩张状态观测器相结合的自抗扰控制算法,在Matlab/Simulink中搭建了控制模型进行仿真分析,并搭建平台进行实验验证。利用该算法解决了传统PID控制算法在气体静压运动平台存在的扰动问题。结果表明:相比于传统PID控制算法,自抗扰控制算法能够有效减小跟踪误差,降低超调,并且提高了气体静压运动平台的抗干扰性能。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.
