| Abstract: | 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. |

| Keywords: | nonlinear discrete time systems state observers linearization feedback control stability |
