| Abstract: | A classical model-based speed-sensorless field-oriented control method for a general-purpose induction machine is considered.Improved versions of both speed and stator resistance online estimators are presented with the aim of extending control capabilities down tozero speed. Only electrical stator measurements are needed, making the method suitable for general-purpose inverter applications. Online rotorresistance tuning is also included to fully compensate for thermal drift. Performance of the proposed drive is investigated by simulation andexperiments. |
