摘要
提出一种简单、可靠的船舶柴油机缸套冷却水系统建模与仿真分析方法,利用阶跃响应法获取现场试验数据,采用"两点法"得出模型参数,在MATLAB软件环境下,采用"曲线拟合法"对模型参数进行修正,实现系统动态特性建模。对模型进行了仿真分析与实验结果比较,表明模型是可信的。
A kind of simple and reliable method of modeling and simulation for marine diesel engine cylinder cooling water system was provided.In this method,the experimental testing data was obtained based on the step input,and the model parameters were gotten by the two-point method.Then those parameters were modified by the curve fitting method by MatLab/SIMULINK software.The results of the model experiment were very closed to the results of simulation,which indicates the model is correct.
