可控被动式减摇水舱控制策略研究

从未减摇和装减摇水舱后的船舶运动方程出发,对可控被动式减摇水舱的水舱控制策略进行了研究,指出应从充分发挥减摇水舱的性能角度出发,选择水舱的最佳控制策略。从能量最少角度考虑,当波浪频率远离船舶谐摇频率时,可以考虑选择关闭水舱的方式进行控制。仿真结果表明,存在一个最佳控制策略,能够使水舱的性能得到充分发挥,这时水舱减摇效果最高。

Research on Control Strategy for Controllable Passive Anit-rolling Tank

Based on the motion equations of the ship without anti rolling tank and the ship with anti rolling tank,a detail reserch is made on the control strategy for the controllable passive anti rolling tank.The research indicates that selection of optimal control strategy of anti rolling tank should be based on giving full play to the performance of the tank.In order to minimize energy consumption,it can be taken into account to take the way to close the tank when wave encountering frequency is far deviating from the resonance oscillation frequency of the ship.Simulation results indicate that there is an optimal control strategy,which can give full play to the performance of the anti rolling tank and bring maximal stabilization effectiveness to the ship.
