Direct Torque and Flux Controlled Space Vector Modulated (DTFC-SVM) Based on Fuzzy Logic Controller for Line-Start Permanent Magnet Synchronous and Permanent Magnet Synchronous Machines
Abstract
In this paper, Direct Torque and Flux Control (DTFC) method based on Space Vector
Modulation (SVM) technique is designed for a Line-Start Permanent Magnet Synchronous Motor (LSPMSM) and its equal Permanent Magnet Synchronous Motor (PMSM). In addition, the LSPMSM is designed using finite element analysis. Moreover, the same Fuzzy Logic Controllers (FLCs) with minimum simple triangle membership functions and reduced rule bases are designed and used. In order to present a thorough comparison, the same conditions are tested for both motors. Simulation results from MATLAB/Simulink software are presented for independent control of torque and flux motor parameters, and the advantages of the proposed method for the LSPMSM over the PMSM are analyzed.
