基于粒子群算法的调距桨螺距与转速优化匹配

PSO-Based Optimal Matching Between Pitch and Rotational Speed Run of Main Engine for Controllable Pitch Propeller

提出一种基于粒子群优化算法的螺距与转速优化匹配控制算法,将传统“分段式”控制模式与优化后的联合控制模式下的螺旋桨工作效率进行比较,结果表明可以得到螺距与转速的最佳匹配曲线,经验证该优化算法对提高船舶推进效率具有明显效果,可以实现航速的连续最佳控制。

For controllable pitch propeller ship, the realization of the optimum matching between the pitch and the rotational speed of the main engine in the whole speed range can improve the propulsive efficiency and reduce energy consumption. Aiming at the joint control mode, an optimal matching control algorithm of pitch and rotational speed run of main engine based on particle swarm optimization algorithm was proposed. By comparing the working efficiency of the propeller under the traditional "segmented" control mode with the optimized combined control mode,the results show that the optimum matching curve of pitch and rotational speed run of main engine can be obtained. After comparison, it is proved that the optimization algorithm has obvious effect on improving the ship propulsion efficiency and can realize the continuous optimal control of the speed.
