Abstract: To study the performance characteristic of FADEC which is the most important components in the control system of a certain aeroengine, a test system reflecting the performance characteristic was established. In consequence the system outline, hardware , software and data acquisition and handling were discussed in detail. A control software can be concluded from the data based on the test system, which will be used in the FADEC system design. The simulation results show that the system has the advantages of being convenient and practical.
