Abstract: A method of controlling supercharging pressure in an internal combustion engine, wherein the supercharging pressure is controlled by controlling a control amount for operating a supercharging pressure control device. The control amount is controlled in feedback control mode responsive to the difference between the actual value of the supercharging pressure and a desired value thereof when the supercharging pressure is in a steady state, and at the same time a learned value of the correction value is obtained by calculating values of same applied during the feedback control.
