| 摘 要： | 根据传热学的相关理论,对船舶主机缸套冷却水系统的传热进行分析,给出了系统的热力动态数学模型.针对目前船舶主柴油机缸套冷却水系统惯性较大,缸套冷却水出口温度经常超调的特点,可以在现有的传统PID反馈控制的基础上,引入以船舶主柴油机输出功率作为反映缸套冷却水热负荷扰动的信号的前馈控制,以减小缸套冷却水出口温度的动态偏差,并利用MATLAB仿真进行了验证.结果表明,前馈-反馈复合控制能有效减小最大超调量和缩短调整时间,改善控制效果.

| Abstract: | A dynamic mathematic model has been established by analyzing the heat transfer mechanism in the cylinder liner water cooling system of main marine engine using the transfer theory.Aiming at the reduction of dynamic deviation of the outlet temperature of liner cooling water caused by the larger inertia of cooling water system,the output power of main engine is taken as a feed forward control of the thermal loading disturbance signal of liner cooling water on the basis of current traditional PID feedback cont... |
