    摘要： Methods and apparatus are provided for aligning a control reference axis with a magnetic north of a permanent magnet motor. The method includes the steps of injecting a predetermined stator current on an estimated reference axis of the permanent magnet motor and introducing predetermined error on the estimated reference axis. The method further includes the steps of determining if a speed of the permanent magnet motor is greater than a predetermined threshold speed and setting the control reference axis to 180° added to the estimated reference axis if the speed of the permanent magnet motor is greater than the predetermined threshold speed or setting the control reference axis to the estimated reference axis if the speed of the permanent magnet motor is less than or equal to the predetermined threshold speed.

    摘要： Systems and methods are disclosed to provide torque linearity in the field-weakening region for an electric (e.g., IPM) machine. The systems and methods implement a field weakening and a torque linearity control loop for linearizing torque generated by an electric machine. First and second voltage commands are used at the field weakening loop to generate a first adjusting current command. The first adjusting current command is then provided to the torque linearity control loop, where it is multiplied by a gain to generate an output current command, which can then be limited to generate a second adjusting current command. The second adjusting current command can then be added to a current command to generate an adjusted current command. The first adjusting current command can also be added to another current command to generate another adjusted current command. The adjusted current commands and feedback currents are then used at a synchronous current regulator to generate new first and second voltage commands. As a result, torque linearity is maintained when the electric machine operates in the field weakening region.
