<P>PROBLEM TO BE SOLVED: To provide a motor control device which drives a synchronous motor, including compensation for parameter fluctuation of inductance Lq caused by an abrupt change of load, under non-interference control, to suppress degradation in control performance. <P>SOLUTION: The motor control device has a first voltage compensator (3) which calculates a first compensating voltage vector applied to a voltage command vector based on an inductive voltage vector, a current error vector calculator (13) which calculates a current error vector between a detected current vector and an estimated current vector, and a second voltage compensator (4) which calculates a second compensating voltage vector applied to the voltage command vector based on the current error vector and the current command vector. <P>COPYRIGHT: (C)2009,JPO&INPIT |
