random sea wave disturbance

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.
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。
