摘要： A control system for a motor including a rotor comprises a sensorless sensor module that includes a saliency-based estimator module that generates a first rotor position signal based on saliency and a back electromotive force (emf) estimator module that generates a second rotor position signal based on back emf. A selector selects the first rotor position signal for rotor speeds below a first rotor speed and the second rotor position signal for rotor speeds above the first rotor speed. A rotor position sensor senses a position of the rotor and generates a third rotor position signal. A fault detection module senses faults in the rotor position sensor and outputs the third rotor position signal when a fault is not detected and one of the first and second rotor position signals when the fault is detected. An indirect field oriented control (IFOC) system controls the motor based on a selected one of the first, second and third rotor position signals.

摘要： A method for controlling an electric machine having current sensors for less than every phase of the electric machine includes operating a processor to perform a test to preliminarily determine whether a fault exists in one or more of the current sensors and a test to finally determine that the fault exists in the one or more current sensors. The method further includes operating the processor to utilize a state observer of the electric machine to estimate states of the electric machine, wherein the state observer is provided state input measurements from each non-faulty current sensor, if any. Measurements from the current sensor or sensors determined to be faulty are disregarded. The processor controls the electric machine utilizing results from the state observer.

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.
