A sensor () detects the angle of the output shaft () of a synchronous motor (). A multiple rotation processing unit () converts the angle of one rotation or more that is detected by the sensor () into a multiple rotation angle. A phase difference FB unit () performs feedback control in such a way that the phase difference between the electrical angle and the mechanical angle of the synchronous motor () is a target phase difference (). A position FB unit () performs feedback control in such a way that the multiple rotation angle after conversion by the multiple rotation processing unit () is a target position ().

Control device and control method for actuator

An attaching system of an exhaust gas recirculation valve includes: an attachment unitto be communicated with an exhaust gas circulation passage of an internal combustion engine; and an exhaust gas recirculation valvethat is fitted to the attachment unit and that has an exhaust gas passage to be communicated with the exhaust gas circulation passage, wherein the exhaust gas recirculation valve has a water-cooled passageto be communicated with a water-cooled passagefor cooling the exhaust gas passage provided with the attachment unit, when fitted to the attachment unit.
