| 摘 要： | 针对标准ADRC因内部fal函数存在拐点而产生抖振的问题，研究了一种改进型的自抗扰控制器。该控制器采用PD控制器替代了非线性状态误差反馈控制率（NLSEF），并针对扩张状态观测器（ESO）的拐点抖动进行了改进，并通过MATLAB/Simulink进行了仿真实验，仿真结果表明，采用此种方式的改进型ADRC控制器超调效果得到改善，响应速度加快，在控制精度和抗干扰能力上有较大提升。

| Abstract: | Aimed at the chattering problem of standard ADRC due to the inflection point of internal fal function,an advanced ADRC was studied.The PD controller was used to replace the nonlinear state error feedback control rate(NLSEF),and the inflection point jitter of the extended state observer(ESO)was improved,the simulation results show that the overshoot effect of the advanced ADRC controller was improved,the response speed was accelerated,and the control accuracy and anti-interference ability were greatly improved. |
