With the development of simulation technology, the hardware -in -loop real -time simulation technology has been widely applyed to control system research and design. Research of semi - physical simulation in inlet/exhaust pressure adjustment system is very important in application. This paper dctailedly introduces the effect and key technologies of semi - physical simulation technology on aero engine altitude simulation test, semi - physical simulation test stand building scheme of inlet/exhaust pressure adjustment system based on GE90 - 70 programmable control system. The contrast analysis of the simulation and other normal test results shows that the dynamic simulation model development is correct and valid, the semi - physical simulation test system of design can show the real tests running at the real- time control system.
