依据舵减摇状态空间模型,推导舵减横摇广义预测控制律,在舵角舵速约束的条件下,采用二次型规划计算控制量进行减横摇控制.对某一船舶在典型航行工况下进行了系统仿真,仿真结果表明,该方法不但可取得35%～45%的减摇效果,而且对横摇角速度与横摇角加速度也有40%左右的减小效果.

According to the state-space model of ship, a generalized predictive controller was obtained in conditions of the constraints of rudder angle and rudder angle rate. Then the controller was applied to the rudder roll stabilization. The system simulation of a certain ship was done under the typical navigation condition. The result shows that this method is effective not only for the roll angle but also for the roll angle rate and acceleration. The anti-roll effectiveness can reach 35%～45%. The anti-roll angle and anti-roll angle acceleration effectiveness can reach 40% or so.
