<P>PROBLEM TO BE SOLVED: To provide a motor control apparatus that can efficiently suppress a pulsation vibration of a motor. <P>SOLUTION: A motor control apparatus 1 includes: rotation control means 3 for rotatively controlling a motor 2; an acceleration sensor 4 as vibration detection means for detecting a vibration of the motor 2 during rotation; particular frequency component extraction means 5 for extracting a vibration component of a particular frequency from the vibration detected by the acceleration sensor 4; vibration component decomposition means 6 for decomposing the vibration of the particular frequency into a main vibration component of the particular frequency and a pulsation vibration component superimposed on the main vibration component; and repetitive control means 7 for generating a compensation signal to suppress all the main vibration component and pulsation vibration component simultaneously and inputting it into the rotation control means 3 repeatedly. <P>COPYRIGHT: (C)2012,JPO&INPIT |
