Title:
METHOD AND APPARATUS FOR SENSORLESS POSITION CONTROL OF A PERMANENT MAGNET SYNCHRONOUS MOTOR (PMSM) DRIVE SYSTEM
Document Type and Number:
WIPO Patent Application WO2007070814
Kind Code:
A9
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.
