Abstract
The present teaching includes a speed control of a side shaft of a drive train connected to a dynamometer on a drive train test stand in which a torque (M) caused by the longitudinal force (F) calculated in a simulation model is additionally transferred to the control unit, and from this a compensation torque (M) is calculated in the control unit as a function of the longitudinal force (F) caused by the torque (M) and a deviation (A) between a moment of inertia (J) of the dynamometer and a moment of inertia (J) of the simulated vehicle wheel, the control unit calculates a torque (M) from the setpoint speed (n) with a speed controller and a torque (M) to be set with the dynamometer is calculated as the sum of the compensation torque (M) and the torque (M) calculated by the speed controller and set by the dynamometer.
