Abstract
A supercharging pressure control system for supercharged internal combustion engines includes a supercharging pressure control valve for controlling supercharging pressure of intake air, supplied by a supercharger. A desired value of the opening of the supercharging pressure control valve is determined depending on operating conditions of the engine. When the supercharging pressure detected has reached the desired value of the supercharing pressure, a feedback control mode is selected, in which the opening of the supercharging pressure control valve is controlled so as to make the supercharging pressure detected equal to the desired value of the supercharging pressure. On the other hand, when an actual value of the opening of the supercharging pressure control valve determined during the feedback control becomes smaller than the desired value of the opening of the supercharging pressure control valve, an open-loop control mode is selected, in which the opening of the supercharging pressure control valve is controlled to the desired value of the opening of the supercharging pressure control valve.
