<P>PROBLEM TO BE SOLVED: To provide a torsional vibration restraining device equipped with an inertia control unit capable of further restraining even feeble vibration in a torsional vibration restraining part. <P>SOLUTION: The torsional vibration restraining device comprises an inertia control means 29 for calculating and outputting an inertia control signal T<SB>MJC</SB>from a motor acceleration torque signal T<SB>MAFB</SB>obtained by multiplying a differential signal of a motor average velocity signal N<SB>MAVG</SB>by an inertia time constant τ<SB>M</SB>, a motor acceleration torque control means 28 for calculating a torque command compensation signal T<SB>RFL</SB>from a deviation signal between a signal TR<SB>FAX</SB>obtained by subtracting T<SB>MJC</SB>from a torque command signal T<SB>RFAx</SB>and the motor acceleration torque signal T<SB>MAFB</SB>, and a motor torque control means for controlling the current of a motor so as to obtain motor torque corresponding to a torque command T<SB>RFM</SB>as the total of T<SB>RFA</SB>and T<SB>RFL</SB>. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
