Improvement to an electronic system for adjusting the position of an object which makes it possible to locate it without it needing to be seen and which consists of three parts: a control system, an impulsion device and a positioning sensor. The control system consists of an electronic circuit which controls the position of the object by means of a linear or circular potentiometer. The electronic circuit is formed by a working voltage- stabilising circuit formed with four linear amplifiers and a power stage. This improvement is designed for application as a system for opening and closing vehicle windows, blinds, awnings, theatre curtains and drapes. <IMAGE>
