Aero-engine acceleration process rotating speed control method

The invention relates to the field of aero-engine rotating speed control, in particular to an aero-engine acceleration process rotating speed control method. The aero-engine acceleration process rotating speed control method comprises the steps that stability margin requirements under different rotating speeds are obtained, and the initial fuel supply amount under the current engine state is determined; fuel is supplied to the engine according to the initial fuel supply amount, the working state of the engine is determined, and the rotating speed of the engine and stable working margin information of the engine are output; engine stable working margin and engine rotating speed information are received and fed back to a control system, and feedback margin demand information is obtained; feedback margin demand information is received and compared with a given margin demand under the current rotating speed, and given fuel increase and decrease amount information is obtained according to the difference value of t
