Abstract
A programmable, closed-loop four quadrant control system for a switched reluctance motor employs feedback control, angle control and current control. The feedback control can be implemented with a speed feedback loop and/or a torque feedback loop. The angle control digitally synchronizes stator phase current pulses with rotor position, and the current control acts as a chopping or bang-bang controller to limit magnitude of the stator phase current pulses.
