Abstract: Abstract: The classIXV aircraft is a lifting body without wings, and is actuated through the combination of two body flaps mounted at the aft windward side of the vehicles and RCS thrusters. The accurate reentry guidance and attitude control approaches are studied in this paper. Firstly, a numerical predictorcorrector guidance law with flight path constraints is designed to enhance the robustness and accuracy of guidance system. Secondly, a hybrid control law is proposed, with the yaw axis performed by the RCS thrusters, and both the longitudinal and lateral axes performed by the RCS and aerodynamic flaps. Furthermore, robust servo LQR method is used to design the control parameters rapidly. Finally, Monte Carlo simulation is presented to validate the high accuracy and robustness of the proposed algorithm.

Key words: Keywords: intermediate experimental vehicle (IXV), reentry, numerical predictorcorrector guidance, hybrid control
