Provided is a feedback control device comprising: a detector for detecting an output value on the basis of the control subject; a P control circuit which comprises an analog circuit that uses a detection value of the detector and a target value as inputs for a differential amplification circuit and outputs a P control component (VP) to the output of the differential amplification circuit; an I control unit for outputting an I control component (VI) by integrating the deviation between the detection value and the target value through digital processing; and a drive element for controlling the control subject by being driven on the basis of the P control component (VP) from the P control circuit and the I control component (VI) from the I control unit. |
