Abstract :
An adaptive dynamic surface control scheme is designed to achieve output tracking for a class of nonlinear output feedback system with uncertain actuator failure pattern, value and time instants. State observer is used to estimate unavailable plant states. Detailed stability analysis is carried out to prove the uniform ultimate boundedness of all closed-loop system signals.
