| Abstract: | The existence of reduced-order observers for a class of discrete-time nonlinear systems is dis-cussed in this paper.For a given Lyapunov function,under the condition that the observation error is as-ymptotically stable,a reduced-order observer design method of the discrete nonlinear system is given.Fi-nally,a numerical example is presented to illustrate the effectiveness of the design method. |
