Abstract
A controller for a switched reluctance machine, the machine comprising two concurrently energised phases and two concurrently non-energised phases. The controller is configured to, in an injection stage, inject a signal into the two non-energised phases; in a measurement stage, determine a current in each of the two non-energised phases; and in a calculation stage, apply an algorithm to the determined currents to determine a rotor angle.
