ABSTRACT:
An electric drive control apparatus for an electric machine, includes a controller that computes an instruction value based on an electric machine rotational speed and a target electric machine torque that represents a target value of an electric machine torque, generates a drive signal based on the instruction value, computes a voltage saturation variable that represents a likelihood of an occurrence of a voltage saturation, determines whether a switch condition for switching a control between an asynchronous PWM control and a synchronous PWM control is met based on the voltage saturation variable, and selects and outputs the drive signal and switches the control between the asynchronous PWM control and the synchronous PWM control based on a determination as to the switch condition.
