たことを特徴とする自動制御装置。[Scope of Claim for Utility Model Registration] In an automatic control device for feedback control that compares the value of a controlled variable with a target value and performs a correction operation to make the two coincide, A digital filter to which an operation signal is given based on a comparison with a feedback signal, a disturbance detection means for detecting vibration as a disturbance and outputting a corresponding detection signal, and controlling by analyzing the frequency of the detection signal of the disturbance detection means. An automatic control device comprising filter characteristic variable means for varying the filter characteristic of the digital filter so as to increase the gain near the frequency of the disturbance in the loop.
