Abstract
A control device for an internal combustion engine, in which vibration of a waste gate valve in a fully closed state and disadvantages caused due to the vibration thereof while the internal combustion engine is running are prevented, and valve opening responsiveness of the waste gate valve can be improved. In a control device for an internal combustion engine, an opening degree of a waste gate valveis controlled by controlling an electrification duty ratio Iduty of the motor. In addition, a fully closed period duty ratio IdFC, which is an electrification duty ratio Iduty when the opening degree of the waste gate valveis controlled to be in a fully closed state, is controlled such that the fully closed period duty ratio IdFC becomes smaller when a detected engine speed NE of an internal combustion engine () increases (Stepin FIG., FIG.).
