Abstract
This invention relates to an improved device for reducing the lag of position of a non-linear copying system or subsidiary controller for a regulation loop, which comprises a comparator establishing the difference which enters in a multiplier from which emerges a signal sent into another comparator elaborating the difference between this signal and the difference between the frequency and the frequency reference, so that the output of this comparator is introduced into the integral action circuit of the subsidiary controller.
