Model Simulation of Electronic Unit Pump Diesel Engine Oriented to Control

To broaden the application range of hardware in loop simulation for electronic controlled unit, study on model simulation of electronic unit pump diesel engine oriented to control is made, the requirement and selection of simulation model oriented to control in electronic unit pump diesel engine is provided, model of simplified nonlinearity in diesel engine and electronic unit pump system are established in Matlab/Simulink, model verification shows that this model can achieve relative accuracy, by means of calculation time and parameter, different calculation step and method affecting model output is analyzed and compared. Real engine model is applied into hardware-in-loop simulation test, its results show that model can perform real-time ECU hardware-in-loop simulation test accurately.
