A new, the torque and speed sensorless induction motor control is proposed, analyzed and experimentally verified in this paper. The control is based on stator and rotor flux as state variables. This choice of state variables allows a graphical representation which is transparent and insightful. A speed sensorless implementation of the control is demonstrated experimentally for low speed operation...
This paper presents a speed sensorless non-salient permanent magnet synchronous motor (PMSM) sliding mode control algorithm. The key idea is to integrate the benefits of the variable structure system control design and the event-driven sequential control structures to raise the system performance and control efficiency. The operation at low speed is improved by reducing the disturbance impact. The...
