Abstract

Reaction control system (RCS) is used for reusable launch vehicle (RLV)' attitude control, which is different from the atmospheric steers control, so a well designed control system to fit the attitude control in high altitude is required. In this Paper, a ping pong control structure with dead zone was proposed for attitude control, angular motion was simplified in order to convenient for control law designing, the feedback control laws for pitching, rolling and yawing were designed, and the stability of the whole control system was analyzed using describing function method. Simulation shows that the control system is satisfied, finally, Comparison between the attitude control effect and jet flux was analyzed.

Key words： RLV; RCS; attitude control; ping pong control; describing function method
