description The invention discloses a piezoelectric actuator hysteresis compensation method for helicopter rotor vibration control. A piezoelectric actuator for helicopter rotor vibration control is installed ona helicopter rotor, a piezoelectric actuator hysteresis compensation method and a helicopter rotor vibration controller are combined so that the hysteresis nonlinear effect of the piezoelectric actuator is compensated, a desired flap deflection angle output by the vibration controller is input into a hysteresis compensator so that driving voltage is obtained, and through the flap deflection angleobtained by the piezoelectric actuator and the corresponding hub load, input and output control is finished so that helicopter rotor vibration control is realized. The piezoelectric actuator hysteresis compensation method realizes the piezoelectric actuator hysteresis compensation of helicopter rotor vibration control, improves performances of the helicopter rotor vibration control system and hasan important theoretical va
