摘要 主要结合可重复使用运载器的特殊工作环境、任务需求和实际的工程硬件的可实现性提出了修正脉冲调宽RCS系统指令处理逻辑,使用具有离散性能的推力器对控制律给出的线性变化控制量进行近似拟和,与常规的基于死区的处理方法相比较,既保证了姿态控制系统对指令姿态的跟踪能力,稳定性能达到期望要求,同时姿态角速度和角度的振荡频率降低到1Hz以下,RCS系统燃料消耗降低57%,也不会对推力器性能产生苛刻的要求。最终的仿真结果验证了该方法的有效性和适用条件。 So base on the special environment, mission requirements and hardware limit, this work give a revised pulse wide modulation method for RCS command logic. Comparing with dead zone method for RCS command logic, this method make keep on attitude control system tracking ability and stabilization ability. And the violation frequency of angle rates is less than 1 Hz, the cost of fuel decrease to 57% of that in former method. The final simulation result shows the validity and using condition of this method.
