In this paper,a high-gain nonlinearobserverbasedfaultdiagnosis approach is proposed for a general class of nonlinearuncertain *** nonlinear system under consideration contains parameter uncertainties as well as Lipschitz-like nonlinearities and may be harmed by time-varying *** faultdiagnosis algorithm is designed based on a new adaptive estimation method for estimation of the parameters related to *** main result is given in a constructive manner by developing a novel nonlinearadaptiveobserver,without resort to any *** design of the proposed observer does not necessitate the resolution of any dynamics systems and its expression is explicitly *** global exponential convergence is ensured,which does not rely on solving any kind of dynamic Riccati equation.A simulation example is given to illustrate the efficiency of the proposed faultdiagnosis method.
