| 摘 要： | 推力分配是动力定位控制算法中的重要组成部分,在满足执行机构的物理约束和任务使用约束的同时将高层控制器的指令转化为底层执行机构的控制输入,实现期望控制指令的最优化实施。本论文采用改进的推力分配算法对配备直翼推进器的船舶进行约束条件下的推力分配优化研究,并以某型工程船为背景进行仿真验证,结果表明相比逻辑算法该优化算法效果更佳。

| Abstract: | Thrust allocation is a key part of DP control algorithm. This part converts the instructions from high-level controller into the input of bottom controller, taking restrictions of actuators and tasks into consideration. This paper gives an optimized thrust allocation algorithm, which can promote accuracy and reduce power consumption in the DP mode of vessels equipped with VSP. The simulation of this algorithm on one engineering ship shows the result is better compared with the logical algorithm. |

| Keywords: | optimized thrust allocation algorithm DP VSP |
