<P>PROBLEM TO BE SOLVED: To increase a vibration damping control effect by reducing phase differences between a presumed value of motor rotational speed and actual motor rotational speed, in a vibration damping and control device. <P>SOLUTION: A control block 22 performs filtering, having a characteristic of Gm(s)/Gp(s) to calculate a first torque target value Tm1<SP>*</SP>. A control block 31 inputs a motor torque command value and deduces the rotational speed of a motor 5. A control block 33 calculates a second torque target value Tm2<SP>*</SP>, based on a deviation between the deduced value of the motor rotational speed and its detected value. An adder 34 adds the first torque command value Tm1<SP>*</SP>and the second one Tm2<SP>*</SP>, to calculate a torque command value. A time delay controller 35 makes time delayed by a prescribed time, including the delay time starting from the time, when the torque command value is outputted, until the time a motor actually generates command torque, and then outputs the torque command value to the control block 31. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
