Abstract In this paper, application of neuron-based adaptive control system, instead of PID control system, to
main engine cooling water temperature regulation system is proposed for the improvement of control and energy
saving. Then the main engine high temperature fresh water cooling system is chosen as the research object. After
modeling of each of the main devices in the system, the model of the whole system is established, and neuron
based adaptive control system is applied according to the model. The simulation results show that the properties of
neuron-based adaptive control is better than that of PID control, and the neuron-based adaptive control system is
more suitable for control of main engine cooling water temperature.
Keywords Main engine, cooling water temperature regulation, neuron-based adaptive control, simulation

船舶当运行工况发生变化时,主机负荷的变化幅度较大,并对主机冷却水温度调节系
统产生较强烈的扰动.另外,船舶出于降低营运成本的目的而越来越多地安装轴带发电机
组,使主机负荷的波动较频繁.而船舶主机的冷却水温度控制系统是个集水,电,机为一
