What is Sensorless Control of Induction Motors about?

This document summarizes a study on sensorless vector control of induction motors at very low speeds. It presents a novel system that uses offset voltage vector estimation and online estimation of stator and rotor resistances. Speed is estimated from the difference between estimated synchronous and slip speeds. Rotor resistance estimation is based on the error between commanded and actual reactive power. Stator resistance estimation uses the error between commanded and measured stator current magnitude. Sim
