Abstract

The servo control system has an integral channel for controlling an operation element (8) for regulating a process (8, 4) of which a variable "final" state is represented by a signal (M, I). A "limited variation" variable state must not exceed a "permitted" interval between a high and a low limit. The servo system controls the operation element (8) by using an actuating signal (A) so that the measuring signal (M, I) approaches as closely as possible a level signal (C), (R) furnished by the element (8). The control system has a blocking signal producing circuit. This circuit includes an integration blocking decision circuit. The latter receives high and low level saturation signals and a difference signal (EC). The decision circuit produces the integration blocking signal in two cases. The first (second) cases respectively are when the decision circuit simultaneously receives a high (low) saturation signal and a positive (negative) difference signal.
