Study on Aero-Engine Electronic Controller Design Technology Based on FPGA

A design technique for aero-engine electronic controller based on field programmable gate array(FPGA)is discussed.Considering that the FPGA has the features of parallel architecture,hardware function reconfiguration and hardware/software co-design,a novel distributed aero-engine electronic controller in a programmable chip based on FPGA is proposed.Three key techniques for this controller are then discussed,which named embedded processor selection,hardware co-processor and synchronous data bus design.As a result,a prototype of the controller is implemented based on Altera FPGA-EP2C35,the hardware performance is tested,and the results show that the controller design method is feasible in the current technical condition.The proposed controller based on FPGA can overcome the disadvantages of current centralized electronic controller,such as poor software-module reusability,highly customized system,low development efficiency and poor parallel real-time performance,and reduce the FADEC system life cycle cost.
