Abstract
Disclosed herein are a motor control apparatus and method. The motor control apparatus includes a compensation signal generator configured to apply a DC-Link voltage (V) for driving a motor to a parameter map preset in order to estimate a gain and phase of a motor torque ripple generated when the motor is driven according to a motor command current and a motor rotation speed, and to generate a compensation signal (i) for compensating for the motor torque ripple corresponding to a current input motor command current (i*), motor rotation speed (ω), and DC-Link voltage (V), and a current controller configured to control the current of the motor by controlling an inverter such that a compensation command current (i*_), generated by reflecting the compensation signal (i), in the motor command current (i*), coincides with a motor drive current (i) supplied to the motor from the inverter.
