基于船舶运动控制的Matlab仿真

Matlab Simulation Based on Ship Movement Control

在分析随机海浪的波能谱和船舶的受力情况的基础上,建立随机海浪模型和船舶运动模型。用PID控制方法实现减摇鳍的控制,并用Matlab软件对海浪的波倾角和船舶的横摇角进行仿真。通过比较仿真结果发现,PID控制减摇鳍能使船舶减摇达90%以上。结果表明,该方法可以很好地用于随机海浪作用下的船舶横摇减摇预报。

By analyzing the spectrum of the random ocean wave and of the force of the ship, the ocean wave model and the ship movement model are erected. Use control theory of PID to carry out the control of fin stabilizer, and simulate the slope angle of ocean wave and angle of roll by Matlab software. Can find from the simulation result that PID control theory can reduction the roll by over 90 percents. The result shows that the theory can be used well in forecast of the ship roll reduction under the operation of random ocean wave .
