船舶机动定位技术及其实现方法

Implementation of position control with manoeuvring techniques for dynamic positioning vessels

为改善动力定位船舶在高海情下的定位能力 ,研究了机动定位的控制方式 ,并设计了一种机动定位模糊控制系统。其特点是模仿人类的航海技巧 ,通过充分利用环境力 ,实现船舶的定位与机动。仿真结果表明 ,在高海情下 ,机动定位方式可以实现较高精度的定位控制 。

In order to improve the positioning ability of dynamic positioning (DP) vessels, we have studied the method of position control by manoeuvring (PCM), and developed a PCM fuzzy control system. This control system simulates the natural seamanship skill of manoeuvring and uses the forces exerted by the environment on the vessel to maintain the position or assist the manoeuvring. Simulation results show that the vessel can keep its position precisely in PCM mode with less comsumption of energy in severe weather conditions.
