Abstract
A method of controlling a device comprising an adjusting component which is associated in its operation with a means for actuating the movable element of said component, a means for sensing the actual position of the movable element and a control means, characterised in that it comprises, at the beginning of any operating cycle, initialising the adjusting device by determining the “fully clsoed” and “open to the maximum” positions of the movable element (1″), and indexing the control means (5) and setting its parameters accordingly then, during the consecutive running of the operating cycle, continously or at regular intervals putting the open/closed state of the adjusting component (1″) under the control of the reference signal (SIGN), by adjusting the control signal (IN) which is applied according to the result of comparing the indicated positions of the movable element (1″), obtained firstly from the reference signal (SIGN) and secondly from the (OUT) signal delivered by the sensing means (4).
