METHOD FOR ADJUSTING A CONTROL LOOP, DEVICE FOR GENERATING CONTROL PARAMETERS AND CONTROL DEVICE

The invention relates to a method for boost pressure control of a turbocharger (200, 300) with variable turbine geometry (VTG) or for boost pressure control of a turbocharger (200, 300) with variable turbine geometry (VTG) and simultaneous control of at least one exhaust gas recirculation rate of an exhaust gas recirculation (high-pressure EGR, low-pressure EGR) of an internal combustion engine (100), whose controller parameters (p) vary when controlling a controlled system (12) with a controller (14) as a function of variables (s) of the controlled system (12). It is provided that for the determination of the controller parameters (p) as a function of the variables (s) of the controlled system (12), at least one Gaussian process model (18) is used in a device (16) provided for this purpose for the determination of the controller parameters (p), wherein the determined controller parameters (p) are the outputs of the Gaussian process models (18).
