摘 要：In this paper,considering a class of dynamic systems with external disturbances and actuator faults,a novel observer which can estimate the state and the fault signal simultaneously is *** estimation technology is applicable for the linear system with actuator fault and nonlinear system with Lipschitz ***,the sufficient existences conditions of the observer are discussed;then the structure of the fault observer is constructed to enhance the performance of fault estimation,the H performance robust to the external disturbances is guaranteed through Lyapunov ***,the numerical simulation results demonstrate the effectiveness of the proposed method.
