In a dual-inverter type of motor control apparatus which controls a synchronous motor having two or more open-end armature windings corresponding to respective phases, first and second inverter control circuits control the motor by supplying voltage commands to corresponding ones of the two inverters, with a combination of respective control methods executed by the inverter control circuits for generating the voltage commands being determined such as to provide a high speed of control response, while preventing control interference caused by effects of component characteristic disparities, such as deviations between timings of updating the voltage commands by the two inverter control circuits.
