Design and HIL Simulation Verification of Open Electronic Control Based on TTP/C Bus

Open electronic controller with good modularity, high reliability, easy maintenance and low life-cycle cost is one of the possibilities of the aeroengine electronic controller in the future. An open electronic controller with 3 smart nodes was designed based on self-designed TTP / C bus. Interface between the host controller and bus controller, signal on speed and oil needle position collected, closed-loop control and speed closed-loop control were achieved. HIL simulation verification was carried out with FADEC (Full Authority Digital Engine Control) system interface simulator. Results show that smart node of the open electronic controller can achieve reliable and real-time engine control, it has advantages such as good real-time performance, high safety, and convenient maintenance.
