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.

摘要： A control architecture for an electrical inverter includes a command limiter that is realized as a circular voltage limiter. The command limiter includes a Cartesian-to-polar converter coupled to a command source such as a synchronous frame current regulator. The Cartesian-to-polar converter provides magnitude and phase components for d-q command voltages. The command limiter further includes a magnitude limiter that limits the magnitude component to the maximum fundamental voltage component of the inverter, and a polar-to-Cartesian converter that converts the limited magnitude component and the phase component into modified d-q command voltages.
