Modified Whale Algorithm-Based Optimization for Fractional Order Concurrent Diminution of Torque Ripple in Switch Reluctance Motor for EV Applications

This work proposes a new multi-objective optimization technique for concurrent diminution of torque ripple with the regulation speed 75 Kilowatt, 8/6, 4-phase SRM based on double close loop, modified whale algorithm optimized fractional order proportional integral (MWAO FO-PI) control commutation angle controller. The system is analyzed and designed in MATLAB/SIMULINK environment. First, performance MWAO tested 30-dimensional standard benchmark functions. It found that better when examined functions, compared WOA, another six recently proposed state-of-art Then, loop FO-PI controller implemented was percentage improvement achieved combined objective function 10.044% comparison PI controller, 9.0597% WOA also proved FO-PI-based provides less ripple, tracking reference value current profile From all above analysis, conclusion reached very good overall operational controllers. simulation analysis experimental validation lacking.
