AN ACCELERATION ADAPTIVE CONTROL FOR TURBOSHAFT ENGINE OF HELICOPTER
-
Abstract: A scheme of an acceleration adaptive fuel control is put forward for helicopter turboshaft engine.The scheme is based on GG/P *2 closed loop control with adaptive control rule,which corrects the demand of og/P *2 closed loop control PID with surge flag detected by sensed compressor discharge pressure during the engine acceleration,since the engine performance deterioration or damage will initiate the surge in this time.This scheme also provides altitude compensation and surge recovery P *2.It requires only modifying a litte the hardware of an existing FADEC,but mainly the fuel control microcomputer software,so it is easy to upgrade an existing FADEC to the adaptive control level.
