Simulation Research of Engine’s Electronic Control System Based on Modular Modeling Method

Abstract:

Abstract. Modular modeling method was adopted to build model for the engine’s electronic control system , including the engine system model, sensor model, controller model and actuator models. For the engine system, the modeling approach of the average value was used to establish an air supply system model, the fuel supply system model and the engine power take-off model. By the method of mathematical fit, a mathematical model of electronic control engine’s sensors was established. Based on Mat-lab/Simulink, it designed simulation system and proceeded simulation tests for each model of engine control system, then the results show that the model is correct, and it can manifest the changes of relevant parameters during the actual operational process of the engine.
