ALEXANDRIA, Va., March 5 -- United States Patent no. 12,244,250, issued on March 4, was assigned to Tula eTechnology Inc. (San Jose, Calif.).
"Feedback scaling for electric machines" was invented by Andrew W. Phillips (Rochester, Mich.).
According to the abstract* released by the U.S. Patent & Trademark Office: "A control system for an electric machine, wherein the electric machine has a maximum bus value (Vbus) is provided. The control system is configured to determine a feedforward vector (VFF), determine a feedback vector (VFB), compare a magnitude of a sum of the feedforward vector and feedback vector (|VFF+VFB|) and the maximum bus value (Vbus), when |VFF+VFB|less than equal toVbus providing a control vector of VFF+VFB to the electri...
