To provide a control apparatus for an internal combustion engine with a supercharger capable of reducing the exhaust pressure of an exhaust path to a predetermined upper limit or less without loss of the responsivity and traceability of the supercharging pressure control system controlling the supercharging pressure in the internal combustion engine with a supercharger. The control apparatus includes a supercharging pressure control unit (110) controlling the supercharging pressure for supercharging an engine (2) with air by changing, within a predetermined opening range, the opening degrees of exhaust flow rate regulating valves (321a, 321b, and 322a) adjusting the flow rate of exhaust gas flowing through the exhaust path of the engine (2), an engine speed determination unit (120) determining whether an engine speed increasing rate at which the engine speed of the engine (2) increases is less than a threshold, and a closing direction limit value changing unit (160) causing the supercharging pressure control unit (110) to control the supercharging pressure by changing a closing direction limit value within the predetermined opening range in an opening direction when the engine speed increasing rate is not less than the threshold. |
