Abstract

A system including a pneumatic actuator having an actuator element, the system further including a compressed-air provision device which is configured to carry out a closed-loop position control of the actuator element by applying compressed air to the pneumatic actuator. The compressed-air provision device is further configured to carry out an assistance procedure in which the actuator element is set in an oscillation movement, pressure values and position values are detected, and, on the basis of the detected pressure values and the detected position values, friction information and/or mass information is determined and/or verified.
