PROBLEM TO BE SOLVED: To control a motor more accurately, by coping with nonlinearity of each coefficient appearing in a torque equation. SOLUTION: The information indicating nonlinearity of d- and q-axis primary inductances Ld and Lq of a motor against d- and q-axis currents Id and Iq of the motor is found through experiments, etc., and when the motor is actually controlled, the current command (vector) to the motor is decided by utilizing the information. Since the nonlinearlity of the d- and q-axis primary inductances of the motor is reflected in the control of the motor, the motor can be controlled more accurately. |
