摘要
研究了离散时间非线性最小相位系统的动态输出反馈镇定 .首先对离散时间非线性系统引入了逼近渐近稳定性的概念 .基于此概念 ,提出了一种动态补偿器设计的新方法 .主要结果是 ,如果一非线性系统的零动态是逼近渐近稳定的 ,则能用动态输出反馈镇定 .
We study the problem of stabilization of discrete-time minimum phase nonlinear system via dynamic output feedback. The concept of approximately asymptotic stability is introduced. Based on the concept, we propose a new method for design of dynamic compensators of discrete-time minimum phase nonlinear system. The main result is that a discrete-time minimum phase nonlinear system is stabilizable via dynamic output feedback if its zero dynamics is approximately asymptotically stable. The design of dynamic compensators is constructive.
