System for automatic position control, applicable in particular to a set of moving objects moving in an autonomous manner on a guide path by virtue of a driving electric motor 9, characterised in that it comprises, on each moving object: - a means 13, 14 for generating pulses whose frequency F1 represents the actual speed of displacement of the moving object; - a first counter 12 for counting the said actual speed pulses; - a second counter 11 for counting reference pulses whose frequency F0 represents the target speed desired for the moving object; and - a comparator means 17 for comparing the contents of two counters 11, 12 and generating a corresponding error signal epsilon acting on a variable speed drive 16 in order to modify as a consequence the speed of rotation of the driving electrical motor 9 of the moving object. <IMAGE>
