A controller includes a target frequency determining unit, first and second acceleration sensors, and a predetermined variable calculator. The target frequency determining unit determines a target frequency from a vibration state of a vibration source. The first acceleration sensor obtains a first acceleration of a mass member. The second acceleration sensor obtains a second acceleration of a vibration controlled member. The predetermined variable calculator calculates a predetermined variable of a transfer function of the first acceleration with respect to the second acceleration at the target frequency. If the predetermined variable is a numeric value other than 0, the controller changes a magnetic force generated in an electromagnet.
