Abstract
A motor drive control apparatus for performing motor control that is stable and has a good efficiency includes: a speed processing unit that generates a first value by converting a second value corresponding to a current speed into a duty ratio; a torque processing unit that generates a third value by converting a fourth value corresponding to a target torque into the duty ratio; and a drive unit that controls switching by a switch included in a complementary switching amplifier by an average duty ratio corresponding to a sum of the first value and the third value to drive a motor connected to the complementary switching amplifier.
Claims23
A motor drive control apparatus, comprising:
- a speed processing unit configured to generate a first value by converting a second value corresponding to a current speed;
- a torque processing unit configured to generate a third value by converting a fourth value corresponding to a target torque;
- and
- a drive unit configured to control switching by a switch included in a complementary switching amplifier by an average duty ratio corresponding to a sum of the first value and the third value to drive a motor connected to the complementary switching amplifier.

- a drive unit configured to control switching by a switch included in a complementary switching amplifier by an average duty ratio corresponding to a sum of the first value and the third value to drive a motor connected to the complementary switching amplifier;
- and
- a calibrating unit configured to calibrate a second conversion coefficient in the torque processing unit based on a reference value of a first conversion coefficient in the speed processing unit, a value of the first conversion coefficient, which is calibrated so that a motor drive current becomes zero when the fourth value is zero, and a reference value of the second conversion coefficient.
