DRIVE APPARATUS WITH MOMENT OF INERTIA ESTIMATION

摘要

The invention relates to a method for operating a controller apparatus (2) for controlling a drive apparatus (1) which has a load moment (M) and a moment (J) of inertia. During a constant-running phase in which a drive speed (12) of the drive apparatus (1) is kept at a constant setpoint value (14) by the controller apparatus (2), an estimated load value (25) of the load moment (M) is ascertained by a load moment estimator (26). Pilot control of the moment of inertia should be performed in the constant-running phase. To this end, a model (23) of the drive apparatus (1) is provided, said model describing a relationship between the moment (J) of inertia and the load moment (M). An estimated inertia value (24) of the moment (J) of inertia is provided on the basis of the model (23) during the constant-running phase.
