摘　　要：针对传统采用线性反馈的自抗扰控制器在误差收敛速度方面的不足,结合自抗扰控制思想,采用扩张状态观测器和非线性误差状态反馈的复合型控制策略,利用扩张状态观测器(ESO)观测系统扰动并进行前馈补偿,再通过引入非线性误差状态反馈(NLESF)生成控制量,使系统能够兼顾跟踪性能和抗扰性能,提高误差收敛速度。给出线性反馈和非线性反馈的跟踪性能和抗扰性能的对比理论分析,通过仿真对比PI,P+ESO,NLESF+ESO三种控制方式,验证了NLESF+ESO的复合型结构具有更快的误差收敛速度和更强的抗扰性能。Aiming at the shortcomings of traditional linear feedback active disturbance rejection controller in error con⁃vergence speed,combining with the idea of active disturbance rejection control,the compound control strategy of nonlinear error state feedback and extended state observer(NLESF+ESO)was adopted.ESO was used to observe system disturbances and perform feedforward compensation,and nonlinear feedback was introduced to generate the control quantity which ena⁃bles the system to take into account both tracking performance and anti⁃disturbance performance,and improves the error convergence speed.The theoretical analysis of tracking performance and anti⁃disturbance performance of linear feedback and nonlinear feedback were given.The three control methods of PI,P+ESO and NLESF+ESO were compared through simula⁃tion,which verifies that the compound structure of NLESF+ESO has faster error convergence speed and stronger anti⁃inter⁃ference performance.
