Direct Torque Control based SVPWM Technique for Permanent Magnet Synchronous Motor Drives using Torque and Flux linkage Estimators

A new approach to improve the performance of PMSM dynamically, a Direct Torque Control (DTC-SVM) scheme of Permanent Magnet Synchronous Motor (PMSM) is vividly presented in this paper. Based on valid depth technical analysis of PMSM mathematical model and the operating principle of Direct torque control system, MATLAB/ Simulink is used to establish a simulation model of this system, and extensive research of simulation is conducted to present in this paper. An efficient control technique called DTC-SVM for a PMSM is studied and simulated and the results are validated using MATLAB/SIMULINK environment which are clearly present in this paper which has fast response and good dynamic performance.
