ALEXANDRIA, Va., Oct. 28 -- United States Patent no. 12,451,826, issued on Oct. 21, was assigned to Goodrich Control Systems (Solihull, Great Britain).
"Adjustable phase advance for PM motor control" was invented by Andrei Dinu (Leicester, Great Britain).
According to the abstract* released by the U.S. Patent & Trademark Office: "There is provided herein a method of advancing phase of a DQ reference frame in a Field Oriented Control, FOC, algorithm for a permanent magnet motor. The method comprises: monitoring a component of the stator voltage demand of the permanent magnet motor, when the component of the stator voltage demand surpasses a threshold, calculating a phase advance angle, Thetaadv, based on a gain multiplied by the difference...
