摘要： Provided is an active vibration noise suppression apparatus having good robustness without determining a secondary transfer function while not performing adaptive control. A first control unit generates a control signal by a first adaptive algorithm as a direct adaptive algorithm. A storing unit stores an equivalent value Gh of a secondary transfer function G which is adaptively updated as an adaptive filter by the first control unit. A second control unit uses a second adaptive algorithm which uses the equivalent value Gh of the secondary transfer function G stored in the storing unit as a feedforward coefficient and updates a filter coefficient C2 of the control signal as an adaptive filter based on the feedforward coefficient. The second control unit generates the control signal by the second adaptive algorithm when the first control unit does not generate the control signal.
