In a PID control system, a proportionality coefficient multiplication unit multiplies a valve opening degree command value by a proportionality coefficient. A first angle deviation computation unit computes a deviation between an output value from a proportionality coefficient multiplication unit and a detected rotation angle of a valve driving motor. A differential coefficient multiplication unit multiplies the valve opening degree command value by a differential coefficient. A third angle deviation computation unit computes a deviation between an output value from the differential coefficient multiplication unit and the detected rotation angle of the valve driving motor. |
