Abstract :
To solve the sensor failure problem, the nonlinear observer and controller are designed respectively. Under the condition of output measureable only, the paper designs a novel extended Luenberger form observer to estimate convergence state vector and brings forward a new strong adaptive control law based on dynamic surface adaptive backstepping control. Finally, the results are verified by simulation for a 6 DOF hypersonic aircraft.
