Abstract
A control system for use with a motor is disclosed. The control system may have a controller that is configured to receive a torque command for the motor and receive a rotor angular velocity signal indicative of an angular velocity of a rotor of the motor. The controller may also be configured to generate a field weakening command by adding a field weakening adjustment signal to the rotor angular velocity signal, and generate a torque voltage command and a flux voltage command based on the torque command and the field weakening command. Further, the controller may be configured to convert the torque voltage command and the flux voltage command into phase voltage commands and output the phase voltage commands.
