针对一类非线性离散系统 ,首先提出了一种新的容易实现的状态观测器设计方案 ,并证明了观测器的收敛性 .其次设计了系统基于观测器的输出反馈稳定化控制器 .最后给出了数值算例 ,仿真结果表明了本文设计方法的有效性 .

A new kind of simple and easily implementable state observers are proposed for a class of nonlinear discrete time systems,and the convergence of the estimated state towards the true state is proved. Then,the observer based controllers which are used to stabilize the systems are designed.Finally,a numerical example is given to demonstrate effectiveness of the proposed method.
