【Abstract】 A self- designed hardware- in- the- loop simulation system for diesel is introduced,which can be used to improve the effiency of developing engine electronic control units. In this system,a standard per- sonal computer serves as operating console,through which the software is controlled and hardware is con- nected.The diesel model performs well by using floating- point DSP runing at40 MHz.An intelligent in- terface module using 80 1 96microprocessor supports the excellent real- time behavior of the system by transmitting signals between modules quickly and accurately.Common memories are used for saving and delivering data in the system,butwith differenttypes for differentmodules.For the engine simulation,a simplified non- linear model is developed,which could meetthe real- time running demand while the accura- cy is good enough for studying the engine’s dynamics. And the system’s performance is proved by some simulation results provided.更多还原
