    摘要: A rotational signal of a generation source of a control object is detected and, when a rotational speed (frequency) varies, convergence values of filter coefficients of adaptive filters 33, 34 based on a previous control result corresponding to the frequency stored in a control device 11 are retrieved and set to the adaptive filters 33, 34 as initial values. The adaptive filters 33, 34 are updated by using the initial values of filter coefficients and output a control signal y(t) to an ACM (actuator) 3a. LMS arithmetic units 37, 39 read a reference signal calculated from the rotational signal and an acceleration signal (error signal) e(t) detected by a sensor 9 and carry out processing for updating the filter coefficients of the adaptive filters 33, 34. The adaptive filters 33, 34, based on updated filter coefficients, output the control signal y(t) to the ACM 3a.
