ABSTRACT:
An engine or a similar torque generator with internal torque M1 and moment of inertia T1 and an electrical drive with electrical torque M2 and moment of inertia T2 coupled thereto interchange an interchange torque MA over a coupling according to the equation M1=(MA) (1+(5 T)).sup.2 (1.sup.2 +(T1/T2))-M2,(T1/T2). Based on the actual values MA and M2 as well as a parameter (T1/T2)* and a model time constant T*, a model value M* is computed in accordance with this function, which indicates the actual internal torque if said parameters correspond to the actual parameters. Thus, using supplemental set values .DELTA.M2 the preset electrical torque is varied and the parameters calibrated in such a manner that the effect of the M2 variation on the model value virtually disappears.
