A speed sensorless induction motor vector control system using q-axis flux with parameter identification

In this paper, a speed sensorless vector control system for induction motors is presented, which includes rotor speed estimation and stator resistance identification. A linear model of the system is proposed to analyze the changes in observer and speed estimation gains. By computing the trajectories of poles and zeros and the transient responses, the system stability is discussed. The effectiveness is verified by digital simulation and experimental results.
