ABSTRACT OF THE DISCLOSURE In order to determine from a reference vector (for instance from the EMF vector ?s of a rotating field machine given by the current ?s and the voltage ?s ) Image (for instance the flux vector) and to thereby suppress defects of technical integrators and instabilities of the circuit used, a correction vector is formed which is rotated relative to the model vector (angle .epsilon.?) and of which the magnitude is proportional to the derivative of the vector magnitude, or proportional to another volatile quantity. The model vector itself is obtained by integration of the sum vector formed by the reference vector and correction vector. This "voltage model" can optionally be controlled by a reference vector.
