Zusammenfassung:The invention discloses a high frequency noise active suppression method applied to an electric steering engine. The method comprises the following process: vibration information in the flight process is acquired in real time by using an aircraft vibration sensor, and FFT transformation is performed on the vibration information so as to obtain the frequency and the amplitude of high frequency noise; meanwhile, a notch filter is additionally arranged for a deviation signal generated after feedback calculation of the electric steering engine position instruction and electric steering engine current in an electric steering engine control system to filter the deviation signal, the central filtering frequency and the filtering depth of the notch filter are the frequency and the amplitude of the high frequency noise identified by the vibration sensor, and the central frequency and the amplitude of the notch filter are adaptively corrected in real time according to the variation of the frequency and the amplitude of
