可控被动式减摇水舱随机控制策略研究

在"船舶-可控被动式减摇水舱"系统数学模型基础上,根据安装减摇水舱的船舶在随机海浪作用下的横摇运动特点,利用成型滤波器以及在线辨识方法对"船舶-可控被动式减摇水舱"系统横摇运动进行预报,并利用预报信息以及实时测量信号对减摇水舱内液体进行控制,实现船舶横摇运动与水舱内液体运动的相位控制,使减摇水舱在不同航态以及不同海情下均有较好的减摇效果.

Strategic study on stochastic control of passively controlled anti-rolling tank

Based on the model and the motion characteristics of 'ship-passively-controlled-tank',a second-order forming filer was adopted to forecast the ship's rolling by using parameter identification.The predicted signal was utilized to achieve the phase difference holding between the roll and liquid movement,which can achieve effective roll stabilization under different sailing condition and sea state.
