船舶稳性控制系统研究

Research on ship stability control system

稳性控制是船舶航行运动控制的关键环节,由于船舶在海水中航行时会受到规则波、不规则波等载荷的作用,当船舶在外载荷作用下产生的运动超过极限平衡位置时,就可能导致船舶的失稳,造成船舶倾覆等严重事故。因此,船舶领域将稳性控制作为一项重要的研究内容。本文建立船舶运动控制过程多坐标系及坐标转换,利用可控减摇水舱技术设计了一种船舶稳性控制系统,分别从控制系统组成原理、稳性控制系统仿真等展开研究。

Stability control is the key link of ship navigation motion control.Because the ship will be affected by regular waves,irregular waves and other loads when sailing in seawater,when the motion of the ship under the external load exceeds the limit equilibrium position,it may lead to the instability of the ship and serious accidents such as ship overturning.Therefore,researchers in the field of ships regard stability control as an important research field.In this paper,the multi coordinate system and coordinate transformation of ship motion control process are established,and a ship stability control system is designed by using controllable anti rolling tank technology.The research is carried out from the composition principle of the control system and the simulation of the stability control system.
