Speed Sensorless Model Predictive Torque Control of Induction Motors using A Modified Adaptive Full-order Observer

In this paper, a new design of the state observer is proposed to reduce the unstable low-speed region of the adaptive full-order observer (AFO) based speed sensorless speed control of induction motors (IM). The proposed state observer is designed in z-domain rather than in s-domain following the pol...
