Control process for drive train involves detection of disturbing moment of subharmonic vibrations by angle-discrete Fourier analysis

摘要

The control process, implemented by a switchboard (1), is for an engine (5) with a flywheel having two rotating flywheel weights, The rotation rate of the crankshaft is detected by sensors. Torque is regulated to compensate for subharmonic vibrations. The disturbing moment of subharmonic vibrations is detected by angle-discrete Fourier analysis of the crankshaft, and the disturbing moment is regulated phase-sensitively.
