船舶减摇鳍系统H^(∞)控制器设计

Design of H^(∞) Controller in Ship' s Fin Stabilizer System

利用Ｈ∞控制理论对船舶减摇鳍横摇姿态控制系统进行了混合灵敏度设计，并针对船舶减摇鳍系统的特殊性，解决了Ｈ∞控制器设计中与该系统不匹配的有关问题。另外，还提出了一种新的权函数的选择方法用以解决Ｈ∞控制器设计中存在的和对象的频带几乎一致的随机海浪干扰抑制问题。

By using the H∞ control theory,a mixture sensibility design was made for a fin stabilizer system. The mismatch problem in the design of H∞ controller associated with the system was solved in accordance with the features of the ship roll damping. In addition,a new method for selecting the weighting function is proposed for suppression of the random sea wave disturbance with the almost similar frequency band to the controller object in the design of H∞ controller.
