In order to reduce the influence of ground vibration on beam orbit stability, an active vibration isolation platform can be used. In this paper, an active vibration isolation system is proposed, which realizes the inverse dynamic process based on a nano-positioning platform and combines with a proportional controller to reduce the transmission of ground-based excitation to the beam element. The absolute vibration velocity signal obtained from the sensor is input to the controller as feedforward signal. The controller processes the input signal and then the output signal drives the piezoelectric ceramic actuator to generate displacement, realizing the active vibration control. The test results of the prototype show that the active vibration isolation system can achieve 50\% displacement attenuation, which indicates that the vibration control strategy has certain engineering application value in the construction of large accelerators.}}, }
