PROBLEM TO BE SOLVED: To provide a feedback control device capable of improving the control accuracy of a controlled target while suppressing the increase of arithmetic processing load of the control device. SOLUTION: When a control CPU performs interrupt time setting processing as an interrupt time setting part, the control CPU recognizes in a step 110 the output of a PWM signal from a PWM signal output circuit on the basis of an interrupt signal from the PWM signal output circuit. In a step 120, the control CPU sets a duty ratio calculation period by a feedback operation part by adding prescribed timeαto current time when the interrupt signal is inputted.
