To meet the requirement of microturbo engine measurement and control

a set of integrated measurement and control system was designed.The system can implement engine ground test

control system's semi-physical simulation and electric fuel pump test.Signal processing outputs of all sensors were connected to measurement computer and engine Electronic control unit(ECU).ECU receives commands from measurement computer by RS232

and also samples p2 to complete speed control indirectly.Engine speed test and signal processing method

as well as electric fuel pump pulse width modulation(PWM) drive circuit were introduced in detail.Based on engine characteristics analysis

control law was designed.By adopting multithreading programming method

measurement computer software was developed in LabWindows/CVI platform.The application shows that the system test is more efficient and the design scheme is not only simple

but also practical.It can be applied to same kind of engine test and research.
