防空导弹大攻角飞行姿控系统设计

Altitude Control for High Angle-of-Attack

针对大攻角飞行这样一个非线形、时变、耦合系统,提出了一种基于模型参考时变全程滑态变结构控制方法,分别针对滚动通道、俯仰/偏航耦合通道进行了设计分析,最后进行了六自由度仿真,得到了满意的结果。

Based on the time-varying sliding-mode variable structure control theries,a new design scheme for the nonlin- ear time-varying coupling system of flying with large angle of attack is proposed.Design for roll channel and pith/yaw coupling channel is also analised respectively.Finally.the outstanding feature of our design is proved by digital simula- tions results.
