摘      要：The fault diagnosis problem is investigated for a class of nonlinear neutral systems with multiple ***-varying faults are considered and multiple disturbances are supposed to include the unknown disturbance modeled by an exo-system and norm bounded uncertain disturbance.A nonlinear disturbance observer is designed to estimate the modeled ***,the fault diagnosis observer is constructed by integrating disturbance observer with disturbance attenuation and rejection *** augmented Lyapunov functional approach,which involves the tuning parameter and slack variable,is applied to make the solution of inequality more ***,applications for a two-link robotic manipulator system are given to show the efficiency of the proposed approach.
