摘要
Abstract
A composite control algorithm integrating sliding mode variable structure control and active disturbance rejection control(ADRC)is proposed to address the problems of insufficient position control accuracy and dynamic response hysteresis in the aircraft active sidestick system.The ADRC algorithm based on the sliding mode control law is highly insensitive to the model error,parameter fluctuation,and external perturbation of the control object,which can significantly improve the disturbance rejection capa-bility and position control accuracy of the active sidestick.Meanwhile,for the nonlinear disturbance prob-lems such as the friction torque of the active sidestick system and the weight force torque of the sidestick,the influence of the unknown disturbances on the control effect is reduced by adopting a reduced-order ex-tended state observer to estimate the total system disturbances and compensate them into the controller.Simulation results show that the algorithm reduces the automatic centering error by about 86％and the centering time by 12％compared with the traditional linear ADRC,and it can effectively resist the external disturbance torque in the range of 18 N·m.In addition,compared with the traditional PID algorithm under added perturbation,the tracking error of the improved active sidestick position control algorithm is reduced by about 83％,which proves that the control algorithm has better control accuracy and disturbance rejec-tion capability in the position control of the active sidestick system.关键词
