Abstract

This paper deals with the actuator fault diagnosis and accommodation problem for the aero space vehicle (ASV). A novel nonlinear robust adaptive observer is developed for estimation of the actuator fault under the Lipschitz condition on the nonlinear part of such systems, which is used to continuously accommodate the control signal, so as to ensure the stability of faulty system. Finally, simulation results about ASV are presented to illustrate the feasibility and effectiveness of the proposed methods.
