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

This study performs a dynamic modeling and analysis of the axial uniform demagnetization rotor of a motor to investigate the demagnetization peculiar for permanent magnet synchronous motor (PMSM). First, the air-gap change in the motor is analyzed by constructing a dual coordinate system of stator and rotor, and the unbalanced magnetic pull (UMP) model under uniform demagnetization and eccentricity is constructed. Second, combined with the UMP and the self-gravity, a dynamic model of the rotor under a uniform demagnetization and eccentricity is established. Lastly, the accuracy of the mathematical model of UMP under uniform demagnetization and eccentricity is confirmed by the mutual corroboration of Maxwell simulation and MATLAB calculation; and based on the dynamics model, the dynamic characteristics of the rotor system under different degrees of uniform demagnetization are studied. This study provides a theoretical basis for the accurate demagnetization fault diagnosis and vibration control of PMSMs in the future.
