Abstract

A method for monitoring an actuator in a physical system, including: providing a computer model that describes the actuator, the behavior of the actuator being represented by a computer model function and by one or more parameters of the computer model function; determining or adapting the values of the parameters of the computer model with the aid of one or more particular system quantities; determining an error when a specified error condition is fulfilled, the error condition defining when at least one of the parameters, and/or at least one quantity determined from a plurality of the parameters, lies outside a corresponding specified target deviation range for the relevant parameter or the relevant quantity.
