FIELD: technological processes.
SUBSTANCE: embodiment of method includes determining if a first position of a process control device is a first end position, and in response to the first position being the first end position, calculating a second end position of the process control device based on the first end position and configuration information. The embodiment of method additionally includes calculating a partial stroke zone of the process control device based on the first end position and the second end position, and determining when a current position of the process control device is within the partial stroke zone. The embodiment of method also includes calculating an output bias based on a control signal and a summed value when the current position is within the partial stroke zone.
EFFECT: improving the calibration accuracy.
