【Abstract】 A robust fault detection scheme based on adaptive-fuzzy state observers for affine nonlinear systems is presented,and adaptive-fuzzy systems is adopted to repair nonlinear parts.To guarantee the robustness of observers under the external disturbance and the internal system parameter error,the stability theorem is proposed and proved in detail.The simulation results demonstrate the efficiency and robustness of the method for disturbance and system parameter uncertainty.更多还原
