摘要

The invention regards an arrangement for the execution of a control procedure in order to give a magnitude, sensed by means of one or more sensing means a constant value or a course varying according to a given rule, "the preference value", said control taking place under influence of some means with a known transfer function. The new part of the invention is that the sensing means is arranged to transfer to an amplifyer a control pulse of electric nature, and that the amplifyer comprises one or more amplifyer means, each of them having two inputs as well as reaction circuit from the output of said amplifyer, connected to one of the inputs. Filters are provided in the reaction circuit of such a type that they will give the amplifyer a transfer function which has same general character as the inversed shape of the transfer function of the controlled magnitude.
