一种拟无模型的鲁棒控制方法——开关控制新析

A Quasi-Modelless Robust Control Approach ——A New Analysis of Switching Control

给出一种直接跟踪输入信号的控制方法 .该方法将输入与输出的误差符号信息馈送到系统的输入端作为控制信号 ,对各种缓变输入信号直接进行跟踪控制 .该方法只需要很少的控制对象的先验知识 ,设计与调节简便 ,对参数扰动和未建模动态具有鲁棒性 ,控制效果好 ,是一种拟无模型的鲁棒控制方法 .

This paper proposes a new tracking control by using the sign of output error. It can track various kinds of slowly varying input signals directly. It is featured by quasi modelless, good dynamical and static performance, easy design and adjustment, robustness to parameters and unmodelled dynamics disturbances. Theoretical analysis and simulations of this paper verify the above conclusion.
