混合H_2/H_∞鲁棒控制在飞行控制中的应用

Application of mixed H_2/H_∞ robust control to aircraft

利用混合 H2 / H∞ 鲁棒控制技术 ,研究飞机纵向控制系统的综合问题。针对飞机控制系统含有大量的非线性和不确定因素 ,用混合 H2 / H∞ 鲁棒控制方法设计线性状态反馈控制器 ,使飞机控制系统在鲁棒稳定条件下 ,满足一定的性能指标。在国产某飞机纵向控制系统中的应用表明 ,所提出的方法是实用的和有效的。

Flight movement system is a nonlinear system with uncertainty. Linearization also brings uncertainty into system model. In this paper, we use the technical of mixed H 2/H ∞ robust control to analyze flight movement system. The system is robust stable under the resulting state feedback controller and is optimal in the sense of H 2 norm. Application to an aircraft made in China shows our results is effective.
