摘要
大气层外飞行器的姿态控制一般采用姿控发动机的喷气控制,姿控发动机的推力水平直接影响到姿态控制的效果。从稳态推进剂消耗、抗干扰能力以及控制平稳性的角度对姿控发动机的推力设计要求进行了理论阐述。在此基础上,得到一个综合的指标函数,对其进行了优化和仿真验证。
The attitude control of the exoatmosphere vehicle is usually realized by the attitude control thrusters (ACT), and the thrust of ACT has great influence on the control effect. A theoretical elaboration on the thrust designing requirements is offered concerning the steady propellant consumption, capacity of resisting disturbance and control stability. Based on this, a composite index function is presented, the optimization is carried out and simulation results are shown.
