Claim:
1. An adaptive control device comprising: a controller which outputs an operation value to a controlled target in response to a command value input to the controller; and a parallel feed-forward compensator which outputs based on the operation value, a compensation value used for compensating a feedback value of a controlled value output from the controlled target; the controller being configured to perform feedback control in such a manner that the controller outputs the operation value based on the command value and the feedback value which is a sum of the controlled value output from the controlled target and the compensation value output from the parallel feed-forward compensator; wherein the parallel feed-forward compensator includes: an identification section which sequentially estimates a frequency response characteristic of the controlled target; and an adjustment section which adjusts the compensation value based on the estimated frequency response characteristic, wherein the adjustment section is configured to adjust the compensation value by multiplying by predetermined coefficients, a frequency and a gain in which a phase lag of the controlled target is equal to or greater than a predetermined value based on the frequency response characteristic.
