Advanced Torque Ripple Minimization of Synchronous Reluctance Machine for Electric Vehicle Application

The electric machine and the control system determine performance of vehicle drivetrain. Unlike rare-earth magnet machines such as permanent synchronous (PMSMs), reluctance machines(SynRMs) are manufactured without magnets. This allows them to be used an alternative machines. However, one main drawbacks this is its high torque ripple, which generates significant acoustic noise. most typical method for reducing ripple employ optimized structural design or a customized technique. objective paper use approach minimize effects issue in SynRM. work performed two steps: Initially, reference current calculation bloc modified reduce machine. A calculating optimal currents based on stator joule loss proposed. proposed compared methods literature, FOC MTPA methods. comparative study between three rate shows that reduction ripple. second contribution minimization propose sliding mode control. suffers from phenomenon “Chattering” affects To solve problem, second-order different approaches provides lowest
