Abstract
A feedback control apparatus includes: a detector configured to detect an output value based on a controlled object; a P control circuit including a differential amplifier circuit and an analog circuit, the differential amplifier circuit being configured to receive a detection value of the detector and a target value, the analog circuit being configured to output a P control component Vto an output of the differential amplifier circuit; an I control unit configured to output an I control component Vby integrating a deviation of the detection value from the target value by digital processing; and a driver element configured to be driven based on the P control component Vfrom the P control circuit and the I control component Vfrom the I control unit to control the controlled object.
