Detection and control method for a moment of torsion and the speed difference of a rotational two-mass system.

摘要

In a detection and control method for a moment of torsion and the speed difference of a rotational system, the drive unit of which can be understood as a flexibly coupled two-mass system, the moment of torsion (MF) and the speed difference (ND) are determined without direct measuring of the actual load speed (NLI) or load position, by comparison of the engine actual speed (NI) influenced by the moment of torsion (MF) and a simulated engine actual speed (N'MI). The speed difference (N'D) thus obtained and the moment of torsion (M'F) are directly proportional to the actual speed difference (ND) and to the actual moment of torsion (MF) and can be fed to the controlled member of the engine (M) for controlling the natural oscillations of the system.
