摘　　要：针对船舶动力定位非凸约束非线性推力分配优化问题,首先建立了推进器功率消耗、磨损、推力误差的优化目标函数,然后分析约束条件,给出优化问题约束不等式,最后将邻域搜索引入遗传算法求解所定义推力分配问题。仿真结果表明该算法对于求解非凸约束非线性推力分配问题具有较强可行性与准确性,能有效降低推进系统功耗,提高船舶动力定位性能。For the non-convex constrained nonlinear optimization problem of DP ship thrust allocation,the optimization objective function considering thruster power consumption,wear and tear,and thrust allocation error is first established,taking into account the constraint inequalities due to thruster constraints.Moreover,the neighborhood search is introduced into the genetic algorithm to solve the defined thrust allocation optimization problem.The simulation results show that this algorithm has strong feasibility and accuracy for solving non-convex constrained nonlinear thrust allocation problems,which can effectively reduce propulsion system power consumptions and improve the ship dynamic positioning performance.
