汽车发动机电子控制半实物实时仿真的实现

研究利用Simulink建立发动机电子控制中进气系、供油系和点火系等系统的仿真模型。运行纯仿真，以修正发动机仿真控制逻辑、控制算法以及系统参数。利用Simulink的I／O模块把发动机仿真模型与数据采集卡连接，再连接真实发动机，实现半实物的仿真。同时利用实时工具RTW模块和Windows Target模块把仿真模型转化为可执行程序，建立仿真模型与仿真程序的连接，从而实现完整的半实物实时仿真系统。利用半实物实时仿真，可在线修改发动机系统参数和控制参数，仿真的结果可以同时体现在真实发动机与计算机上，用来开发、调试及检测汽车发动机电子控制系统。

Realizing the Real-time Hardware-in-the-loop Simulation on Engine Electronic Control by Simulink

The paper describes the simulation models building of an engine electronic control system.With running simulation,we can modify control logic and arithmetic and optimize system parameters.By adding I/O modules to engine models and connecting the models to an real automotive engine,the hardware-in-the-loop simulation can be realized.Using RTW and Windows Target to generate executive program and to build a link of simulation program so that we can realize the complete real-time hardware-in-the-loop simulation.This work can reduce the time and cost in develping the engine electronic control system which has a wide market.
