Resumo
Este trabalho apresenta como contribuição um procedimento para otimização dos ângulos de disparo de um motor de relutância variável via algoritmo de enxame de partículas. Com isso, objetiva-se garantir um desempenho com equilíbrio entre reduzida ondulação de torque e elevada eficiência energética. A técnica é destinada a motores de relutância variável operando na região de controle de corrente, abaixo da velocidade base. O procedimento proposto é comparado com uma abordagem tradicional, de varredura de parâmetros, a fim de mostrar a significativa diminuição do esforço computacional. Resultados de simulação e experimentais são apresentados, mostrando que um balanço entre eficiência e ondulações de torque é alcançado.

Title: PERFORMANCE IMPROVEMENT OF SWITCHED RELUCTANCE MOTORS VIA PARTICLE SWARM ALGORITHM

Keywords: energy efficiency, Particle swarm optimization, Switched Reluctance Motor

Abstract
This paper presents as a contribution a procedure to optimize the firing angles of a switched reluctance motor via the particle swarm optimization algorithm. This aims to ensure performance with a balance between reduced torque ripple and high energy efficiency. The technique is intended for SRMs operating in the current controled region, below the base speed. The proposed procedure is compared with a traditional parameter sweeping approach in order to show the significant decrease in the computational effort. Simulation and experimental results are presented, showing that a performance with a balance between efficiency and torque ripple is achieved.
