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： The present invention is related to the method to find the rotor flux angle from stator voltages and currents by injecting high frequency signal. The injected signal is not rotating one but fluctuating one at a reference frame rotating synchronously to the fundamental stator frequency. The difference of impedances between the flux axis and the quadrature axis at high frequency signal injected on the rotor flux angle is explained by the equivalent circuit equation of the induction machine. The difference is verified by experiments on the test motors at various conditions. The sensorless field orientation control method is proposed and experimental results clarify the satisfactory operation of the method with 150% load torque at zero stator frequency.

The method of controlling the distributed-power-generation system comprises: sensing a rotation speed of a rotation axis of the motor/generator unit; comparing the sensed rotation speed and a predefined reference speed; and supplying a current to the motor/generator unit to produce a load in the opposite direction of rotation of the rotation axis or in the same direction.
