摘要
基于无源系统理论,该文讨论了一类不确定非线性系统的鲁棒输出反馈控制问题。通过虚拟串联微分多项式到系统的输入端,回避了无源化方法所需的相对阶为1的条件,并进一步利用切换控制完成了虚拟串联后的控制器实现。仿真结果证明了本文算法的有效性。
Based on the passivity system theory,the robust output-feedback control for a class of uncertain nonlinear systems is discussed.By cascading a differential operator to the input of original system,one main restriction in feedback passivation design that the relative degree should not be bigger than 1 can be removed.The controller with cascade compensation can be realized by using the switch control.The simulation results verify the effectiveness of the proposed approach.
