  • The engine speed in warm condition was controlled by feed-forward and proportional feedback according to the characteristics of electronic fuel injection (EFI) engine and the requirements of engine speed at different phases in unmanned helicopter.The smooth transition from low to normal speed condition was achieved by speed feed-forward,load feed-forward,speed parameter model and feedback PID(proportion,integration,differential).The normal speed was controlled by using the complex scheme of feed-forward,load-forward,auto-trim,difference of rotational speed feed-forward and PID feedback.It proves that the complex control scheme is effective to constant engine speed control by use of the engine ground test at drive simulation platform.
