摘　　要：船用设备的多样性导致交流电力系统负载变化频繁且快速,对船舶柴油机电子调速器的控制要求越来越高。对此,电站负荷分配控制器多采用拟合频率及功率偏差并对其进行补偿的方式进行负荷分配。主要研究模糊PID控制算法在负荷分配控制器上的应用,优化调节脉冲有效电平占空比输出,从而提高柴油发电机组的负荷分配控制性能。Today, ship power systems are facing more frequent rapid load fluctuations. This is demanding for the governor of the ship diesel engine. The power systems are normally equipped with the load distribution device which adjusts the load distribution according to the measures of the frequency/power variation. This paper develops the fuzzy dynamic optimization PID algorithm for adjusting effective duty ratio which will enhance the load distribution performance of the ship load distribution device.
