Abstract
Methods and apparatus are provided for generating zero-sequence voltages based on voltage commands and a motor output signal. At least one of the methods includes, but is not limited to, receiving a torque command and generating three-phase voltage commands based on the torque command. The method also includes, but is not limited to, generating a motor output responsive to the three-phase voltage commands and generating three-phase zero-sequence voltage samples based on the three-phase voltage commands and the motor output.
