摘要： A control system for an electric machine includes a flux weakening module, which includes a voltage magnitude calculator that receives d-axis and q-axis command voltages and that generates a voltage magnitude. An error circuit compares the voltage magnitude to a reference voltage and generates an error signal. A controller receives the error signal and generates a feedback flux correction signal. A limiter limits the feedback flux correction signal to a predetermined flux value and generates a limited feedback flux correction signal. A feedforward stator flux generating circuit generates a feedforward stator flux signal. A summing circuit sums the feedforward stator flux signal and the limited feedback flux correction signal to generate a final stator flux command.

The method comprises the steps of adjusting a first current command in response to a first voltage error to produce a first adjusted current, adjusting a second current command in response to a second voltage error to produce a second adjusted current, limiting each of the first and second adjusted current below a maximum current, converting the first adjusted current to a first potential, converting the second current command to a second potential, and supplying the first and second potentials to the permanent magnet motor.

摘要： A system for measuring speed of a high-speed motor using a moving average filter. A position sensor generates a rotor position signal. A signal processing module determines a rotor angle from the rotor position signal. A speed observer module calculates a raw speed of the motor from the rotor angle. A filter module selectively generates a filtered speed of the motor from the raw speed of the motor. A frequency-to-period converter module calculates a rotor period from one of the raw speed of the motor and the filtered speed of the motor. A divider module calculates number of points in a moving average from the rotor period. A moving average filter module adjusts a window size of the moving average to the rotor period. A moving average filter removes ripple and harmonics of the ripple from the raw speed of the motor.

摘要： A system and method for controlling an IPM synchronous machine in a vehicle that calculates an operating trajectory of the machine on-line. The system defines three operating ranges of the machine based on voltage magnitude, where a first operating range is controlled by a current limit of the machine and second and third operating regions are controlled by a voltage limit of the machine. The system calculates d- and q-axis current reference signals in the reference rotor frame for each of the three regions. The system determines which set of current reference signals will be used to control the machine based on the operating region. The third operating region is used during over-modulation of the machine.
