<P>PROBLEM TO BE SOLVED: To improve responsiveness of feedback control while maintaining an operation cycle. <P>SOLUTION: In one cycle time TA for outputting voltage commands vd, vq, sampling timings ta, tb for detecting motor currents IU, IV, IW at a sampling cycle TB are set two times. The cycle time TA has a first data acquiring step for acquiring the motor currents IU, IV, IW at the first sampling timing ta, a temporary storage step for storing either the motor currents IU, IV, IW or the processing data obtained by processing the information of the motor currents IU, IV, IW or both of them as temporarily stored data, a second data acquiring step for acquiring the motor currents IU, IV, IW at the second sampling timing tb, and a voltage command operating step for operating the voltage commands vd, vq by using the temporarily stored data and the acquired motor currents IU, IV, IW in the second data acquiring step. <P>COPYRIGHT: (C)2010,JPO&INPIT |
