Abstract
A control circuit includes a proportional control unit configured to calculate a proportional value of a difference between an operating value fed back from an object to be controlled and a target value, as a first output value, an integration unit including a suppressing section, the integration unit configured to calculate an integrated value by adding the difference and a previously-calculated integrated value as processed by the suppressing section, and a second output value based on the integrated value, and an output unit configured to output, to the object, a control signal having a value based on the first and second output values. The suppressing section modifies the previously-calculated integrated value to be in a predetermined range if the previously-calculated integrated value is outside the predetermined range.
