遗传算法及其在船舶运动控制器优化中的应用

Application of genetic algorithms in the optimization of ship motion controller

采用十进制基因编码的遗传算法,优化模糊控制器的隶属度函数。同时引入不同思路的变异、选择方法对模糊控制器的隶属度函数位置进行优化,由Matlab编程实现对某货船航向控制的多方面仿真。并作了种群规模、进化代数对模糊控制器性能影响的对比仿真研究。仿真实验表明,遗传算法用于优化船舶运动控制器效果明显。

This paper optimizes the membership function of FLC using GA with the decimal encoding system of the gene. After introducing the different ways of mutation and selection operation, this paper carries on the simulation study in many kinds of situations among the Simulink of Matlab, using a cargo ship as a controlled plant. In addition, it also simulates and studies the system performance through comparing with change of population size and evolving generation.;
