Abstract
A switched reluctance machine uses a Hall-effect device to detect the flux in the flux path for each machine phase. The flux signal from the Hall-effect device is fed back to a controller which compares the flux feedback with a demand signal to produce an error signal. The error signal is used to control the machine flux using a control law function actuating timed switches for each phase.
