The online optimization control of variable inlet guide vane was studied for minimum fuel consumption,and the effect of variable inlet guide vane on the turboshaft .engine was analyzed. Thus, an online optimization method based on variable inlet guide vane was proposed. At last,a simulation test was conducted for online optimization control of turboshaft engine, showing that the specific fuel consumption （SFC） will decreases by 3 %-7% with higher applicability.
