Abstract:
A system for detecting and eliminating harmonic effects in the DQ plane of the non-sinusoidal back EMF voltages is provided. The system is a field oriented controller (FOC) that includes a poly-phase electric machine, proportional-integral-derivative controllers and a microcontroller. The microcontroller not only analyzes a stator current but analyzes a back electromotive force (BEMF) voltages to extract flux vectors of the EMF. These vectors have distortions as a result of the geometries and saturation effects inherent in the electrical machine. Therefore, the microcontroller corrects these defects by transmitting the BEMF vectors and the machine operating points, including the current rotational speed and current, into the algorithm, which in turn develops a command voltage in the DQ frame for the specific operating point. This command voltage is inserted into the control output of the current PI controller so to prevents the non-sinusoidal back EMF voltages from generating non-sinusoidal currents.

Claim (Index 6):
The system of  claim 2 , wherein the microcontroller analyzes a plurality of back electromotive force voltages such that the flux vectors of the plurality of back electromotive force voltages are extracted.
