摘要
研究了大型柔性卫星平台H∞回路成形姿态稳定控制问题。首先利用拉格朗日方程建立了该卫星的动力学方程,描述了系统存在的非结构不确定性,然后设计了H∞回路成形控制器。提出了控制系统所需要满足的鲁棒稳定性和鲁棒性能指标,随后利用H∞回路成形理论设计了卫星的姿态稳定控制器,最后通过数学仿真证明了所设计的控制器的有效性。
The problem of H_∞ loop-shaping attitude stabilization control for a large flexible satellite is investigated. Firstly, the dynamic model of the satellite is established using the Lagrange equation, and the unstructured model's uncertainty is described, then the H_∞ loop-shaping controller is designed. In the process of designing, the robust stabilization and robust performance indexes which need to be satisfied by the control system of the flexible satellite are brought forward in the first step. Subsequently the attitude stabilization controller of the flexible satellite is designed using the H_∞ loop-shaping theory. Finally, the mathematical simulation is conducted to demonstrate the validity of the H_∞ loop-shaping controller.
