An electromagnetic vibration control system is provided to obtain a plated strip with higher quality in a process of continuously plating a strip, and obtain the plated strip with higher quality by controlling vibration generated when transferring a strip plated in the process of continuously plating the strip. An electromagnetic vibration control system comprises: an electromagnet for suppressing vibration of the strip by controlling the amount of an electric current that flows according to control instructions of an inputted current amount and generating Lorentz force, thereby controlling a strip(5) that is transferred after being plated through the intensity of a magnetic field generated through a magnetic pad(130); a gap sensor(140) for measuring a distance between the magnetic pad and the strip; a PID(Proportional Integral Differential) control part(110) for controlling the amount of an electric current that flows to the electromagnet according to initially set target moving distance information, and controlling the amount of the electric current that flows to the electromagnet based on a subsequently inputted PID gain information; and a PID gain control part(150) for calculating PID gain information for controlling a gain of the PID control part required for suppressing the vibration of the strip based on information on the distance between the magnetic pad and the strip measured from the gap sensor, and controlling vibration of a plated strip through a self-tuned PID control for controlling the gain of the PID control part based on the calculated PID gain information.
