Abstract:
Aspects of the present disclosure are directed to controlling an inner effective torque or an effective torque of a drive unit via a unit controlling unit. In some embodiments, the control method may include providing desired values for the inner effective torque or the effective torque and determining actual values for the inner effective torque or the effective torque during operation of the drive unit on a test stand, and in that actuating dynamics of the drive unit are taken into account in the control by means of a transfer function by correcting the desired values of the control with the transfer function or in that for controlling the inner effective torque or the effective torque of the drive unit, a feed forward control of a manipulated variable of the drive unit is used.
