Feedback Control of Nonlinear Discrete-Time Systems Based on Observers
非线性离散系统基于观测器的反馈控制

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.
