摘要: 为了解决大时滞系统中扩张状态观测器的2路输入信号时间不匹配问题,提出了一种A-P(approximation of poles)时间同步自抗扰控制方法。设计一种A-P时间同步结构,削弱了扩张状态观测器的2路输入信号不匹配程度,结合自抗扰控制思想,构造A-P时间同步自抗扰控制器,通过稳定性分析验证了该控制方法的稳定性,并总结了参数整定方法。将本方法与自抗扰控制方法、预测自抗扰控制方法和改进Smith预估自抗扰控制方法的仿真结果进行比较,结果表明:本方法可以有效地提高对大时滞系统的控制性能,具有良好的快速性、稳定性和抗干扰能力。

Abstract: In order to solve the time mismatch problem of two input signals of the extended state observer in large time-delay systems, an A-P (approximation of poles) time synchronous ADRC method was proposed. The A-P time synchronous structure was designed to reduce the degree of the two input signals of the extended state observer. Combined with the idea of ADRC, the A-P time synchronous ADRC was constructed. The stability of the control method is verified by stability analysis, and the parameter tuning method is summarized. The simulation results of this method are compared with the ADRC method, the predictive ADRC method and the improved Smith predictive ADRC method. The results show that this method can effectively improve the control performance of large time-delay systems, and has fine rapidity, stability and anti-interference ability.
Key words: active disturbance rejection control; large time delay system; time synchronization; approximation of poles; stability analysis
