Abstract

A method of controlling a pneumatic actuator for actuation of a pneumatically actuated device. The actuator comprises a piston and a pneumatic cylinder, the piston is arranged to move axially within the pneumatic cylinder. The piston is moved as a function of a pressure in a pressure chamber of the pneumatic cylinder, and the pressure in the pressure chamber is adjusted by a control unit which controls at least a valve and/or a pressure regulator and/or a pressure generating device. A pilot control component, for the control, is determined as a function of at least a sliding friction force and/or at least a static friction force of the pneumatic actuator.
