基于LMI的H_2理论飞行控制器设计

The Design of Flight Controller Based on the H_2 of LMI

根据巡航阶段飞机飞行状态相对稳定的特点 ,就飞机纵向通道系统模型 ,基于线性矩阵不等式 (LMI)方法进行具有鲁棒性能的H2 静态输出反馈控制器设计。仿真结果表明在一定的干扰情况下和模型不确定条件下飞机仍能保持稳定飞行 ,验证了该设计方法的有效性 ,从而为飞机巡航阶段飞行控制器的设计提供了一种方法。

According to the relative stability of flight s ta te during aircraft cruising,an efficient way was introduced to design H 2 stati c output feedback controller based on LMI for longitudinal model. The simulation result shows that the aircraft can hold stable flight under the disturbance and the uncertainty to some extent.So the design was proved possible and efficient, which provides a direction for civil aircraft flight controller design during cr uising.
