Abstract: Real time simulation with real objects is an important step inaeroengine FADEC system research. In consideration of the relationship between turbojet control system simulation, test and future application in aircraft,a missile turbojet digital control real time simulation system with realobjects based on PC/104 was built.The system outline? hardware layout and adaptive predictive control method were discussed in detail. The result ofsimulation test shows that the system not only can control engine completely,but also provides a convenient means for FADEC system reserch.
