摘要
通过对电力推进船舶中央冷却系统的综合分析,建立电力推进船舶中冷系统的稳态换热模型和动态换热模型。对中冷系统的冷却水出口温度的控制方案,进行了传统的PID控制和基于功率的前馈、反馈控制研究,并在此基础上对控制方案计算机仿真,比较两种控制方案的区别。
By means of comprehensive analysis on electrical propulsion ship, the steady and dynamic model are concluded. Traditional PID control and power dependent feed forward-feedback control are studied. Based on this study, simulation of two control schemes is performanced, and the difference between the two control schemes is analyzed.
