| Abstract: | 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. |
