摘　　要：根据船舶减摇鳍控制系统在不同海情下的期望减摇效果,设计了不同的性能指标,运用遗传算法离线优化设计模糊控制器,组建控制系统知识库.控制程序根据船舶实时的运行情况,调用系统知识库中相应的控制器,并在线修正GA-FC控制器的比例因子,进一步增强系统的自适应能力.仿真结果表明,基于遗传模糊算法的船舶减摇鳍在线控制系统,具有很好的减摇控制效果,并减缓了鳍角饱和概率和转鳍角速度,从而降低了鳍伺服系统的功耗.According to the expectation stabilization effects of ship anti-rolling control system under different sea circumstance, we design the different performance index. We optimum design fuzzy controller off-line and set up the control system knowledge library by the use of genetic algorithm. On the basis of the real time running station, control procedure, call the corresponding controller in the system knowledge library, and modify the GA-FC controller＇s proportional ga!n on-line. The simulation result indicates that the stabilizer on-line control system based on GA-FC is the very effective to anti-roll control, and slowdown the saturation probability of fin angle and angle speed of fin rotation, so that reduce fin service system＇s power consumption. This controller＇s structure has some popularization value for it is so simple to realize easily.
