摘　　要：文章讨论了一类具有时滞和干扰输入满足Lipschitz条件的非线性离散系统的观测器的设计问题,其中Lips-chitz条件以分量的形式给出.基于凸优化方法给出了全维鲁棒观测器的设计,对于给定的Lipschitz条件,该观测器使得干扰衰减指数最小.最后通过一个数值例子说明了此设计方案的有效性.In this paper, the issues of observer design for a class of Lipschitz nonlinear discrete - time systems with time - delay and disturbance input are addressed, where the Lipschitz condition is expressed in a component - wise rather than an aggregated manner. It is shown that full - order robust H. observers can be obtained by means of a convex optimization procedure with minimization of the disturbance attenuation upper bound γ〉 0, Finally, an illustrative numerical example is presented to show the effectiveness of the developed approach.
