导弹基于特征结构配置的输出反馈解耦控制

Decoupling Control of Missile by Output Feedback Eigenstructure Assignment

用当前控制领域研究中较为热门的特征结构配置方法 ,解决导弹在大攻角飞行时 ,存在的严重气动交连耦合问题。采用基于输出反馈特征结构配置的解耦控制方案 ,合理配置了闭环系统的特征值、特征向量 ,求取了输出反馈与前馈控制器。仿真结果表明 ,解耦效果好 ,跟踪指令的性能令人满意 ,进一步验证了特征结构配置方法用于解耦控制的有效性 。

A decoupling control system is designed by output feedback eigenstructure assignment for missile to improve the performance of control system. The control law consists of two different parts, one is the output feedback controller and the other is feedforward controller. The simulation is performed to show the efficiency of this method. One can see that both the decoupling control and the tracing effect are satisfactory,so this method is very practical.
