| 摘 要： | 面向一型喷水推进器为动力定位执行机构的单体喷水推进船舶，开展了船舶仿真模型建立、推力分配及进一步动力定位相关控制算法设计与仿真模拟。针对传统的定步长Kalman滤波提出了改进方案，同时考虑到单体喷水推进船舶的特殊性，对推力分配算法进行了优化，并基于荷载前馈的PD控制算法开展了不同工况下的仿真试验。试验结果表明，所提出的喷水推进推力分配算法能够有效控制一型单体喷水推进船舶实现定点、定艏向、移位、转艏等动力定位典型功能，并具备一定抗外部干扰能力。

| Abstract: | For a mono-hull vessel ship which uses two water-jet thrusters as dynamic positioning actuators, the ship simulation model establishment, thrust distribution and further dynamic positioning related control algorithm design and simulation are carried out. An improved scheme is proposed for the traditional Kalman filter with a fixed step length. At the same time, considering the particularity of the single water-jet propulsion ship, the thrust distribution algorithm is optimized, and the simulation of the proposed PD control algorithm based on the load feed forward is carried out under different working conditions. The experimental results show that the proposed water jet thrust distribution algorithm can effectively control a water jet propulsion mono-hull vessel to realize the typical functions of DP, such as fixed point, fixed heading, shift, and turn, and has a certain degree of anti-interference ability. |
