Abstract

A method and device for monitoring a variable, which is controlled in response to a command signal (ys) and a negative feedback value (y), provides a fault indication when a difference value (ys-y) between the feedback value (y) and the command signal (ys) and a first differential with respect to time (y) of the variable are in a predetermined relationship.
