In order to improve the robustness of the discrete high gain observer with respect to noise measurements and enhance the convergence dynamics, we propose, in this paper, a fuzzy supervision for the observation of a class of nonlinear systems. Actually, a suitable tuning of the observer's gain is made by a fuzzy supervisor. Simulation results are given in order to show the performances amelioration relatively to the case where the classical discrete high gain observer is applied.
