Abstract
A method for controlling a pressure regulating valve is described. An actuating value with which the pressure regulating valve is driven is determined from a pilot control value and a controller action which depend on an actual value and a desired value of a controlled variable. In the event of a change in the desired variable, the controller action is limited to a limiting value that preferably depends on the pilot control value.
