This paper presents three current control strategies for a switched reluctance machine (SRM). Two classical controllers are recall : the hysteresis and the proportional-integral controller. Dynamic and current ripples with both controllers are compared and discussed. Then, a new current controller qualified as "hybrid controller" is proposed. It is a combination of the two previous structures. The principle of this controller is detailed and its influence on the current control performance is described. The three strategies are first tested by simulation, and then on an experimental test bench.
