Popis: A novel direct torque/flux control of a sensorless permanent magnet synchronous motor(PMSM) based on sliding mode technique is investigated in this paper. The proposed scheme combines the merits of the direct torque control(DTC), sliding mode controller(SMC), and space vector modulation(SVM). The speed and position of the PMSM are estimated online by adaptive extended Kalman filter(AEKF) based on the measured current signals. To overcome the large ripple content associated with the direct torque, a torque/flux sliding mode controller has been employed. The space vector modulation is combined with the sliding mode controller to ensure minimum torque/flux ripples and provides high resolution voltage control. Experimental works are carried out to show the ability of the proposed scheme at different operating conditions.
