Reentry attitude tracking control for hypersonic vehicles with RCS

An effective reentry attitude control scheme is proposed based on aerodynamic surfaces and RCS for hypersonic vehicle (HSV) attitude control during the initial reentry phase. First, the attitude control model is divided into the outer-loop and inner-loop subsystems. Due to strong robustness and outstanding control performance, the predictive sliding mode control (PSMC) is utilized for the controller design in both subsystems. Then, the switching mechanism and control allocation scheme between aerodynamic surfaces and RCS are proposed. Finally, simulation results demonstrate the effectiveness and robustness of the proposed control scheme.
