Abstract: An apparatus and a method for inverter control are disclosed. A method according to an embodiment of the present disclosure comprises: discretizing, in a continuous time domain, a voltage equation for a motor in a stationary coordinate system in which a zero-order hold and time delay is reflected; and determining a voltage equation for the motor in a synchronous coordinate system in a discrete time domain by reflecting the position and speed of a rotor of the motor.
