反作用控制系统作为可重复使用运载器高空的姿态控制手段,其力矩特性不同于常规的气动操纵面,因此设计适合高空姿态控制特点与要求的控制系统是非常必要的.文中采用了一种带死区的乒乓控制方式,设计了俯仰、滚转和偏航的反馈控制律,采用描述函数法在频率上分析了控制系统的稳定性.仿真结果表明,设计的控制系统能较好的满足高空姿态控制要求,最后对姿态控制效果和反作用控制系统喷量之间的关系进行了分析.

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.
