船舶电力推进系统控制策略仿真研究

本文针对单一的船舶电力推进系统控制策略无法应对所有复杂工况的问题，提出组合控制策略方案。首先基于三种常规电力推进系统控制策略（转速控制、转矩控制、功率控制）各自的适用范围，引入权重函数，定义权重系数，并提出结合粒子群算法优化权重系数的方法，然后搭建船舶电力推进系统仿真模型，模拟船舶复杂工况，验证组合控制策略的适用性。仿真实验结果表明，所提出的组合控制策略方案在应对船舶复杂工况时能充分发挥三种常规控制策略的优势，具有更好的控制效果。

Simulation Research on Control Strategy of Marine Electric Propulsion System

A combined control strategy of marine electric propulsion system is proposed to solve the problem that the single conventional control strategy cannot meet all the requirements under complex working conditions. Firstly, on the base of the application range of the three conventional control strategies (speed control, torque control, power control), the weight function is introduced and the weight coefficients are also defined. The method of using particle swarm algorithm to optimize the weight coefficients is also proposed. Secondly, the marine electric propulsion system simulation model is built to verify the applicability of the combined control strategy under complex working conditions. The results show that the proposed strategy can fully make use of the advantages of the three conventional control strategies under complex working conditions and has better control effects.
