This paper comes up with an appointed-time prescribed performance control (APPC) scheme for hypersonic reentry vehicles (HRVs) with actuator faults, model uncertainties and external disturbances. Firstly, a control-oriented HRVs model is established, which regards the above three factors as lumped disturbance. Then, a fixed-time disturbance observer (FTDO) is employed in order to estimate and compensate the lumped disturbance. Furthermore, based on the active disturbance rejection control (ADRC) framework and backstepping method, an APPC law is designed to ensure the attitude tracking errors reach to the prescribed regions within the appointed time. The closed-loop system is also proven to be asymptotically stable via Lyapunov stability theory. Finally, the numerical simulation results demonstrate the good performance of the proposed controller.
