<P>PROBLEM TO BE SOLVED: To provide a controller capable of obtaining a sufficient vibration control effect even in an area in which the response delay of a rotary electric machine cannot be neglected for the frequency of transmission torque vibration. <P>SOLUTION: A controller that makes a rotary electric machine output a torque for negating transmission torque vibration includes: a rotation vibration extraction part for extracting rotation speed vibration; a vibration frequency calculation part for calculating a torque vibration frequency; a phase lag rotation vibration calculation part for calculating phase lag rotation speed vibration; a fixed coordinate system setting part for representing the rotation speed vibration and phase lag rotation speed vibration by a fixed coordinate system; a rotation coordinate conversion part for performing rotation coordinate conversion of the rotation speed vibration and phase lag rotation speed vibration; a rotation coordinate system feedback control part for calculating a feedback value; a fixed coordinate conversion part for performing fixed coordinate conversion of the feedback value; and a negation torque control part for generating the command value of negation torque vibration. <P>COPYRIGHT: (C)2013,JPO&INPIT |
