Abstract
The torque pulsations in switched reluctance motors (SRMs) are
relatively higher compared to sinusoidal machines due to the doubly
salient structure of the motor. The magnetization pattern of the
individual phases together with the T-i-θ characteristics of the
motor dictate the amount of torque ripple during operation. Both machine
design and electronic control approaches have been used to minimize the
torque ripple in SRMs. This paper presents an extensive review of the
origin of torque ripple and the approaches adopted over the past decade
to minimize the torque ripple. A hybrid torque-ripple-minimizing
controller that incorporates the attractive features of some of the
techniques developed in the past decade is presented along with
simulation and experimental results
