Abstract
A method and apparatus is disclosed for controlling the supercharging pressure in a turbocharger to obtain sufficient turbocharging even in low speed operating ranges. The supercharging pressure is regulated by a variable geometry means and an exhaust bypass valve means, which in turn are responsive to control means which receive feedback correction. The feedback correction is based on calculated controlled variables. Optimum control of the supercharging pressure is accomplished by finding a learning amount based on the feedback correction which in turn is used to modify the calculated control variables.
