The common control strategy has PID control, adaptive control, variable structure control, intelligent control strategy. （ ）
（常见的控制策略有PID控制、自适应控制、变结构控制、智能控制策略。）
The ship in the wave sailing, part of the propeller out of the water, speed surge, and accompanied by strong vibration phenomenon known as propeller flying. （ ）
（船舶在波浪中航行，部分螺旋桨露出水面，转速剧增，并伴有强烈振动的现象称为螺旋桨飞车。）
Ship maneuverability refers to the performance of the ship to maintain or change its motion state according to the intentions of the driver, that is, the performance of the ship to maintain or change its speed, course and position. （ ）
(船舶操纵性是指船舶按照驾驶者的意图保持或改变其运动状态的性能，即船舶能保持或改变其航速、航向和位置的性能。)
Due to the serious pitch and heave, the phenomenon of violent local impact between the hull and the wave is called attack, attack occurs in the bow, the bottom of the bow column or the bottom of the ship after the surface, in a very short time to fall into the water at a large speed will occur attack. （ ）
（由于严重的纵摇和垂荡，船体与波浪之间产生猛烈的局部冲击现象称为抨击，抨击多发生在船艏部，艏柱底端或船底露出水面后，在极短的时间内以较大的速度落入水中时就会发生抨击。）
Uction include fin stabilizer, water tank stabilizer, weight stabilizer, gyroscope stabilizer, rudder stabilizer, Magnus stabilizer, bilge keel. （ ）
（可用于船舶减摇的装置有减摇鳍、减摇水舱、重物减摇、陀螺仪减摇、舵减摇、马格纳斯减摇、舭龙骨。）
