Application of genetic algorithms in the optimization of ship motion controller

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.;
