ABSTRACT:
The boost pressure in a turbocharged internal combustion engine is regulated by closed-loop control. A current performance graph value u(k), corresponding to a desired boost pressure, is determined from a speed/load-dependent performance graph. After that, the current performance graph value u(k) is compared with a previous performance graph value u(k-1). If the current performance graph value u(k) is greater than or equal to the previous performance graph value u(k-1), then the current performance graph value u(k) is transmitted as the process parameter x(k). Conversely, if the current performance graph value u(k) is less than the previous performance graph value u(k-1), then the current performance graph value u(k) is filtered by a PT.sub.2 member after an idle time elapses and is transmitted as the process parameter x(k).
