反作用控制系统在RLV再入复合控制中的研究

Reaction Control System of RLV Blended Control in Re-entry Mode

以再入段的可重复使用飞行器(RLV)控制系统为研究对象,针对RLV再入姿态的气动舵面与反作用力控制系统的特点,提出优化控制选择配置算法把控制力矩指令配置为末端执行机构指令,分别由气动舵面与反作用力控制系统执行。仿真结果表明,该复合控制方法可以弥补某些情况下气动舵面控制的不足,能很好地实现RLV姿态控制,并具有更好的动态性能。

Based on reusable launch vehicle （RLV） control system and characters of both aerodynamic control and reaction control system （RCS） , an optimal control selection allocation algorithm is developed, which deploys control torque commands into the actuators composed of the aerodynamic surfaces and reaction control system. Simulation results show that this blended control method can make up the insufficiency of surface control, and also realize the attitude control of RLV very well, with better dynamic performance.
