Abstract

See full text

A motor control system for determining an offset correction value is provided. The motor control system includes a motor, an inverter, an inverter controller, and a dynamic offset compensation control module. The inverter is configured to transmit the phase current to the motor. The inverter controller determines the phase current to the motor. The dynamic offset compensation control module is in communication with the inverter controller and the motor, and is configured to perform a method at a fixed periodic interval to determine the offset correction value.
