Rotating vector methods for sensorless, smooth torque control of a switched reluctance motor drive

Abstract

This paper has two primary contributions to switched reluctance motor (SRM) control: a systematic approach to smooth torque production; and a high performance technique for sensorless motion control. The systematic approach to smooth torque production is based on the development of novel rotating spatial vectors methods that can be used to predict the torque produced in an arbitrary SRM. This analysis directly leads to explicit, insightful methods to provide smooth torque control of SRMs. The high performance technique for sensorless motion control is based on a rotating vector method for high bandwidth, high resolution, position and velocity estimation suitable for both precise torque and motion control. The sensorless control and smooth torque control methods are both verified experimentally.
