[Object] To predetermine a target vibration level and keep vibration generated at a position at which vibration is to be controlled equal to or smaller than a target vibration level.[Solving Means] A frequency detection means for detecting a frequency of vibration arising from a vibration generation source, a vibration detection means for detecting vibration of a frequency that is equal to the frequency of the vibration arising from the vibration generation source that is detected by the frequency detection means at a position at which vibration is to be controlled, a vibration level conversion means for converting the detected vibration into a vibration level, a vibration means provided at a position that is different from or the same as the position at which vibration is to be controlled, for generating a vibration control force with which the position at which vibration is to be controlled is vibrated, a comparison means for comparing the vibration level with a predetermined target vibration level, and a vibration command generation means for generating, based on a comparison result obtained by the comparison means, a vibration command for reducing vibration so that the vibration level is changed into the target vibration level in a case where the vibration level is larger than the target vibration level, and outputting the generated vibration command to the vibration means are provided.
