Beschreibung
Zusammenfassung:	The invention provides a control device for an internal combustion engine, in which consumption of electricity for driving a waste gate valve is suppressed as much as possible, generation of noise anddeterioration of the waste gate valve caused due to contact between the waste gate valve and other members are prevented, and acceleration responsiveness can be improved. The control device for an internal combustion engine includes a motor (31) driving a WG valve (waste gate valve) (14), and in which a target opening degree (WGCMD) of the WG valve (14) is set in accordance with a running state of an internal combustion engine (1) and a valve opening degree (WGO) of the WG valve (14) is controlled by controlling electrification of the motor (31). While the internal combustion engine (1) is starting or is running with the target opening degree (WGCMD) set to a fully-closed opening degree, an electrification duty ratio (Iduty) of the motor (31) is controlled such that the electrification duty ratio meets a predeter
