An adaptive controller includes an adaptive-signal generator for generating an adaptive signal, which includes a first amplitude filter coefficient and a first phase filter coefficient, in a first transfer path based on an angular frequency of a cyclic signal, which a vibration generation source generates; a first residual-error detector for detecting a first residual error at a first observation point in the first transfer path; an observation-point target-value setter for setting a residual-error target value, which includes an amplitude target value complying with the angular frequency; and a first filter-coefficient updater for updating the first amplitude filter coefficient and the first phase filter coefficient based on the angular frequency, the first residual error and the residual-error target value. Thus, when adding the adaptive signal to the cyclic signal, the adaptive controller can make the residual error, which results from the addition, not equal to zero intentionally. |
