ABSTRACT:
In an automatic control method for moving a final control element, a position sensor delivers actual-position signals representing actual positions of the final control element to a computer, in which said actual position signals are compared with stored desired-position data associated with correcting signals for controlling an actuator for moving the final control element. In dependence on any deviation which is detected between said actual-position signals and desired-value data, the computer corrects the correcting signal so as to eliminate said deviation. To permit said desired-value data to be determined by an automatic operation, the final control element is consecutively moved to two reference positions, which are defined by stops and are disposed at or beyond the ends of the control range of the final control element. The actual-position signals associated with said two reference positions are delivered to said computer as reference position signals, which in said computer are combined with those correcting signals which as reference correcting signals are associated with said two reference positions so as to generate a linear desired-position function in which said desired-position data are related to said correcting signals. After each movement of the final control element to a position within the control range, the computer is operated to detect any deviation between the actual-position signal and that of said desired-position data which in accordance with said function is associated with the last correcting signal.
