Abstract
A polyphase switched reluctance machine controlled by a control system using sensorless position detection. The controller is robust and reliable and operates over the entire speed range of the machine. In the chopping mode, diagnostic pulses of predetermined flux linkage are injected into an idle phase. In the single-pulse mode, position prediction is done using an active phase. A method of starting the machine uses diagnostic pulses in two phases to provide a unique value for position, allowing the drive to start or re-start under full torque.
