Based on the AMESim simulation environment

a turbofan engine control system simulation platform was developed.Using the modularization modeling method

the system was subdivided into different subsystems

such us sensors

fuel system

electronic controller

actuators and the engine itself.Every module was built

tested and encapsulated into the aero-engine control system module library.With the module library

the engine system model could be established easily.Taking main fuel control system

for example

the modularity modeling methods was described.The results show that system model can reflect the complex integration and coupling of subsystem.Combinatorial optimization using system model can improve the system capability.
