基于H_∞混合灵敏度理论的控制器设计及其在垂直攻击中的应用

The Application of H_∞/Mixed Sensitivity Approach to Attitude Control System for a Missile in Vertical Attack

针对导弹采用跃起俯冲方式飞行对目标进行垂直攻击的特点,应用混合灵敏度理论设计导弹纵向控制器,并且在控制器设计之前对加权函数进行合理的选取.最后通过仿真说明此控制器的可行性和鲁棒性.

According to the characteristic of the missile in spring and dive action during vertical attack,the longitudinal control loop of missile is designed on the basis of H∞ control theory. Then, a method of choosing the mixed sensitivity weighting functions is given. Finally, the experiments and simulations are done. The H∞ /mixed sensitivity controller has strong robustness. It shows that H∞ /mixed sensitivity design approach can deal with the aerodynamic parameters uncertainty of missile in the design of missile control system.
