摘　　要：为验证一种新型控制器在船舶柴油发电机组工况切换和并网发电时的控制效果,通过研究船舶电站系统的非线性数学模型,然后基于Hamilton能量理论,设计柴油发电机组的非线性调速励磁协调控制器,最后设计船舶电站仿真系统对所提方法进行验证。仿真结果表明:Hamilton协调控制器在空载启动、负载突变和并网发电的过程中能更好地保持系统的稳定性,因此,Hamilton协调控制相比于传统的比例积分和微分(Proportion Integral Differential,PID)控制器具有更好的控制效果,具有一定的工程应用价值。In order to improve the control effectiveness of marine diesel generator set in condition of switching and grid-connected power generation,a nonlinear speed-excitation coordination controller of diesel generator set is designed by researching nonlinear mathematical model of the ship power station system and applying the Hamilton energy theory. A ship power plant simulation system is designed to verify the proposed method. The simulation results show that the Hamilton coordinated controller better maintains the stability of the system in the process of no-load start-up, load abrupt change and grid-connected power generation. Therefore, Hamilton coordinated control has better control effectiveness than traditional PID(Proportion Integral Differential) control and has certain engineering application value.
