Sensorless control of variable speed drives using switched reluctance machine

The paper deals with various sensorless techniques for SRM. The theory of most these techniques is described and their advantages and disadvantages are discussed. Simulation of a SRM traction drive for an electric vehicle was created and experimentally verified. A selected method is simulated on the base of a real SRM for various operating range and conditions. The method is analyzed from the point of view of several criterions for the SRM traction drive application.
