Abstract

The invention relates to an electric control arrangement for generating analog manipulated variables, having at least one basic controller circuit having a particular controller structure. The transfer function of the basic controller circuit, which is determined by the controller structure, is established with respect to magnitude by means of controller parameters and is supplied with an analog control-difference signal formed from desired value and actual value. A digital adjusting arrangement is provided for simple adaptation to the particular controlling task with the least possible complexity as to computation. The digital adjusting arrangement 34, on the basis of digital input quantities, selects at least one basic controller circuit 12 having a particular controller structure from several basic controller circuits 12 and switches this basic controller circuit 12 into the analog control loop and/or allows a variation of the controller parameters. Moreover, a corresponding method for controlling analog quantities is specified.
