Study of an Engine Electronic Controller's Core Circuit Module Based on DSP and CAN

To meet the demands of complex control algorithm and distributed control,a design scenario of the electronic core circuit module,which was based on DSP (Digital Signal Processor) and CAN (Controller Area Network),was proposed and realized for DEEC (Digital Electronic Engine Control).Several key problems of hardware and software design were expounded,and the hardware-in-loop simulation validated the feasibility of the module.This module can also be applied in integrated flight-propulsion control and distributed aeroengine control,where the high capability of arithmetic calculation and real-time communication are required.
