Abstract :
A novel speed sensorless direct torque control system-SVM-DTC of permanent magnet synchronous motor (PMSM) based on SVM and MRAS is presented. In this paper the various components of the speed sensorless SVM-DTC and the principle of realization are discussed in detail. Finally the simulation results with the application of MATLAB/Simulink show that the speed identification algorithm is accurate and of robustness, moreover, the whole control system has good static and dynamic performances.
