Abstract
A regulator unit for regulating a flap opening of a flap arranged in a mass flow line includes: an analyzer unit which is designed for providing an analysis signal on the basis of a predefined desired pressure difference and a difference between pressures upstream and downstream from the flap; a regulator which is designed for determining a trigger signal from the analysis signal according to a regulating characteristic; and a control element-regulating unit which is designed for regulating the flap opening of the flap in the mass flow line in response to the trigger signal.

A regulator unit for regulating a flap opening of a flap arranged in a mass flow line, comprising:
- an analyzer unit adapted to provide an analysis signal in accordance with a predefined desired pressure difference and a difference between pressures upstream and downstream from the flap;
- a regulator adapted to determine a trigger signal from the analysis signal according to a regulating characteristic;
- and
- a control element-regulating unit adapted to regulate the flap opening of the flap in the mass flow line in response to the trigger signal;
- wherein the regulator unit includes a precontrol unit adapted to ascertain a precontrol signal from the predefined desired flap opening and the predefined desired difference between pressures upstream and downstream from the flap, the control element-regulating unit adapted to regulate the flap opening as a function of the trigger signal and the precontrol signal.
