PERFORMANCE ANALYSIS OF DIRECT TORQUE CONTROLLED PMSM DRIVES USING FUZZY LOGIC

Abstract

Permanent Magnet Synchronous Machines (PMSM) has been utilized as a part of various particular applications. In any case, lately PMSMs have turned out to be more alluring because of improvements in new materials for permanent magnets and in semiconductor innovation for converter design. Late examinations have proposed a few executions applying the Direct Torque Control (DTC) procedure to PMSM engine drives, offering a quick and exact control. This paper exhibits an altered DTC conspire, utilizing fuzzy rationale with Pulse Wide Modulation (PWM) to enhance stator flux and the electric torque by fundamentally decreasing their ripple. The proposed strategy viability has been confirmed by MATLAB Simulation reproductions. These outcomes are contrasted and the ones got with an adjusted DTC utilizing a PI controlled PWM with current limit
