Abstract

Considering the interference and fault problem of unmanned helicopter, and aiming to improve the reliability of the unmanned helicopter aircraft, the fault diagnosis problem of unmanned helicopter is researched. A robust adaptive sliding mode observer is design based on the sliding mode observer theory. Lyapunov discriminant is adopted to ensure the stability of the observer. Finally, the simulations verify the effectiveness of the proposed method.
