| Abstract:The core of ECU Hardware-in-the-Loop test platform is designing a real-time diesel model with high precision. Considering the characteristics of the marine diesel engine which has huge system size and high test cost, based on MATLAB/Simulink, a real-time simulation model of a common-rail marine diesel which is a combination of mean value model and “filling and emptying” was built. By comparing the simulation results in dSPACE platform with the dynamic state experiment results, the accuracy and real-time quality of the model was verified. |
