Torque estimation of permanent magnet synchronous machine using improved voltage model flux estimator

open access: yesIET Electric Power Applications, 2021
A torque estimator for permanent magnet synchronous machines is presented based on flux estimation. The voltage model of the machine (Faraday's law) is employed to estimate the flux where pure integrators are applied to the electromotive force (EMF) of ...
