Abstract

See full text

A method and a device for open-loop or closed-loop control of a process uses an actuator, a position sensor, a process valve, a process sensor, and a tuning stage. n positions of the process valve are approached, and the associated actual position values are detected. The respective actual process values are detected for each corresponding actual position value to thus obtain value pairs of actual position values and actual process values. Correction values are calculated based on the identified value pairs, and position set values corrected with the correction values are determined to compensate for nonlinearities of the process, such that a linear overall behavior is achieved.
