<p>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.</p>
