<P>PROBLEM TO BE SOLVED: To solve a problem that the inductance of a motor is largely varied depending on its current value due to the magnetic non-linearity and the magnetic saturation of the motor, and as a result, a control error occurs in the motor, thus causing the deterioration of control accuracy. <P>SOLUTION: Highly accurate motor control is performed in such a manner that the motor is analyzed by a non-linearity finite element method or the like using a computer, the number of flux linkage of each winding in each current value is obtained, a data table for the number of the flux linkage is prepared, the motor is controlled in voltage by using the information of the data table, and the optimization of a control parameter of the motor is on-line controlled during the control of the motor. <P>COPYRIGHT: (C)2008,JPO&INPIT |
