| Abstract: | It is concerned with the problem of disturbance attenuation with stability for uncertain nonlinear systems by adaptive output feedback. By a partial-state observer and Backstepping technique, an adaptive output feedback controller is constructed, which can solve the standard gain disturbance attenuation problem with internal stability. |
