Incorporating Control Strategies Into the Optimization of Synchronous AC Machines: A Comparison of Methodologies

Abstract

This paper presents a comparison of methodologies to incorporate control parameters into the design optimization of synchronous ac machines. A metric is used to quantify the conflict level between the average torque and torque ripple for an interior permanent magnet machine and a synchronous reluctance machine. Using 2-D finite-element analysis simulations, the results demonstrate that the traditional approach of lumping the control and design variables together can lead to poor designs, especially when the conflict is high.
