Sensorless Speed Control for PMSM Based On the DTC Method with Adaptive System

R. Balachandar, S. Vinoth kumar, C. Vignesh

This paper presents a speed sensorless with direct torque control scheme using space vector modulation (DTC-SVM) for permanent magnet synchronous motor (PMSM) drive based a Model Reference Adaptive System (MRAS) algorithm. The MRAS is utilized to estimate speed and reduced the torque ripple & improves the accurate output. In other hand the use of SVM method reduces the torque ripple while achieving a good dynamic response. Simulation results are presented and show the effectiveness of the proposed method.
