Simulation of turbofan engine main fuel control system based on AMESim

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.
