| Abstract: | The problem of designing observers for a class of discrete-time nonlinear systems is studied.Based on Schur lemma and Lyapunov stability theory,the approach of observer design for a class of discrete-time nonlinear systems is presented.Under appropriate conditions,it is proved that observer proposed assured that the observation error asymptotically converges to zero,Furthermore,feedback design for a class of discrete-time nonlinear systems is considered based on the observer,and sufficient condition is deri... |
