In order to study the high harmonic control for the noise reduction of the electrically controlled rotor, the active noise control experiments are carried out based on the electronic controlled rotor test rig. Rotor noise measurement system and the flap control system are built firstly. On the basis, the amplitude and phase control of different harmonics are carried out in the experiments. The experimental results show that the rotor sound pressure level can be reduced by 4 dB when the rotor rotating speed is 500 r/min; the optimal control harmonic occurr at 2/rev; the optimal control harmonic amplitude is less than 6°, and also the optimal control phase happen between 180°-300°.
