Abstract : We present a new design for continuous-discrete observers for a large class of continuous time nonlinear time-varying systems with discrete time measurements. Using the notion of cooperative systems, we show that the solutions of the observers converge to the solutions of the original system, under conditions on the nonlinear terms and on the largest sampling interval. Our conditions are given by explicit expressions.
