摘要： It is an object of the invention to provide a torsional vibration suppressing apparatus further including an inertia control portion capable of suppressing a feeble vibration in a torsional vibration suppressing control portion. The invention includes inertia control means (29) for calculating and outputting an inertia control signal TMJC from an electric motor acceleration torque signal TMAFB obtained by multiplying a signal acquired by differentiating an electric motor mean speed signal NMAVG by an inertia time constant τM of the electric motor portion, electric motor acceleration torque control means (28) for calculating a torque command compensation signal TRFL from a deviation signal of a signal TRFAX obtained by decreasing TMJC from a torque command signal TRFA and the electric motor acceleration torque signal TMAFB, and electric motor torque control means for controlling a current of the electric motor in order to obtain an electric motor torque in accordance with a torque command TRFM to be a sum of TRFA and TRFL.
