Abstract:

The main objective of this research paper is to improve the performance characteristics of Surface mounted Permanent Magnet Synchronous Motor fed with modified Direct Torque Control using Fuzzy Logic Controller. The modified Direct Torque Control is adopted to analyze the performance of the motor and to achieve improved characteristics of drive system. The proposed control algorithm is developed with a torque hysteresis controller and stator voltage sectors whereas flux controller is abandoned. The overall drive configuration is implemented in SIMULINK/MATLAB. The focus of this investigation is to compare the performance of the motor with the proposed scheme using Fuzzy Logic Controller and Traditional PI Controller. In fact, the effectiveness of proposed drive is validated with various speeds and load disturbances. The obtained results are described the efficacy of the proposed control of SPMSM with speed loop of fuzzy controller than PI controller.<
