The invention provides a continuous periodic signal amplitude-phase decoupling vibration control method. According to the continuous periodic signal amplitude-phase decoupling vibration control method, a continuous periodic signal is converted into a direct current component, a fundamental frequency component, and various high frequency components for independent control based on Fourier transform thought. By constructing a three-parameter decoupling controller (three parameters are respectively amplitude, frequency, and offset of a sinusoidal signal), a problem of a conventional amplitude-phase control strategy of inability of eliminating non-linear load force disturbance static errors is solved, and any continuous periodic signal can be reproduced. The control method provided by the invention is capable of breaking through a constraint of inherent frequency of a vibration exciter, and has a visualized physical significance.
