Abstract

A self-adjusting regulation system comprising a regulator embodying an input adder for forming the difference of the feedback magnitude and the command magnitude as well as a regulation device for forming an adjustment magnitude from such difference. A linearity detector produces a control signal upon the occurrence of a non-linear behaviour of the regulation circuit. A supplementary adder is arranged between the input adder and the regulation device and has its first input connected with the output of the input adder and its output connected with the input of the regulation device, whereas its second input is connected with the output of a supplementary device composed of a number N of similar integration stages forming a series. Each stage contains an integrator and an auxiliary adder, the output of which is connected with an input of the integrator via a control switch which can be actuated by the control signal. Further, the first input of the auxiliary adder is connected via a first multiplier with the first input of the supplementary adder and its second input is connected via a second multiplier with the output of the supplementary adder, whereas the output of the integrator of the last integration stage of the series forms the output of the supplementary device and for the remaining integration stages in each instance the output of the integrator of a given integration stage is connected with the third input of the auxiliary adder of the next following integration stage of the series.
