Abstract :
This paper presents a sensorless predictive torque control. The predictive torque control is based on pre-calculation of the best switching state in order to keep the state variables close to desired values. The control scheme uses a proportional-integral controller inside of predictive control in order to improve the steady state response. The stator flux that determines the stator voltage is pre-calculated by means of predictive torque control and sliding mode observer (SMO) in order to remove the need for speed sensor. The proposed sensorless scheme is verified by means of simulating the control strategy even at a low speed.
