| Abstract: | This paper established a relation between observer design for discrete time nonlinear systems and solution of overdetermined nonlinear equations. Based on the Guass Newton algorithm, a new observer for discrete time nonlinear systems is obtained. The local convergence of the observer is proved, and simulation results are also presented. |
