Study on QEMF Model and Adaptive Full-Order Observer Design for Universal Sensorless Control of IPMSMs
Abstract
A quadratic extended electromotive force (QEMF) model enabled the use of traditional high-speed adaptive estimation methods combined to high-frequency signal injection (HFSI) for full-range sensorless position control of interior permanent magnet synchronous motors (IPMSMs). However, the first QEMF model presented in the literature only works with HFSI in the $q$ -axis, due to the QEMF being a function of the $q$ -axis current derivative. The …
