A novel current controller for constant current injection based characterization of switched reluctance machine (SRM) is proposed here. Unlike conventional characterization methods, where the rotor is locked at a fixed position, the current injection based method maintains the phase current constant while the machine is run at constant speed. The proposed constant current injection scheme yields the...
The closed-loop speed control for a high speed switched reluctance machine (SRM) is studied in this paper. A speed-and-current dual closed-loop control scheme is selected for speeds as high as 50 krpm. The novelty of the proposed control method is inclusion of the inductance profile selection for a flux-bridge rotor. In this paper, the nonlinear SRM is modeled in a linearized form by small signal...
The paper proposes a new switching scheme for the switch reluctance motor (SRM) which results in superior torque and current control over existing schemes. The scheme aims at removing the unnecessary restrictions imposed by the existing hard chopping and soft chopping methods, while retaining the combined advantages of simple implementation and low current ripples and switching losses, respectively...
