<P>PROBLEM TO BE SOLVED: To provide a controller for alternating-current motors capable of carrying out current control at high response speed even in pulse mode. <P>SOLUTION: The controller 10 controls an inverter 3 to control driving of an alternating-current motor 4. Current references iq*, id* on d- and q-axis coordinates are computed based on a magnetic flux reference Φ* and a torque reference Trq*. The output current of the inverter 3 is detected. Based on the deviation between a detected torque component current iq and the computed torque component current reference iq*, the torque component current reference iq* is corrected and magnetic flux weakening control is carried out. <P>COPYRIGHT: (C)2010,JPO&INPIT |
