| titleOfInvention | Method and device for controlling suppression of torsional vibration in motor speed control system |
| abstract | A torsional vibration suppression device comprising a torsional vibration suppression control unit and an inertia control unit for suppressing even feeble vibration. The device has an inertia control means (29) for differentiating a motor average rotational speed signal NMAVG, multiplying the thus obtained signal by an inertia time constant τM of a motor unit, calculating an inertia control signal TMJC from the product of the multiplication, i.e., a motor acceleration torque signal TMAFB, and outputting the signal TMJC, a motor acceleration torque control means (28) for subtracting the inertial control signal TMJC from a torque command signal TRFA, generating a differential signal representing the differential between the remainder, i.e., a signal TRFAX and the motor acceleration torque signal TMAFB, and calculating a torque compensation signal TRFL from the differential signal, and a motor torque control means for controlling the current of the motor so that the motor torque may be the one in compliance with a torque command TRFM that is the sum of the torque command signal TRFA and the torque command compensation signal TRFL. |
