Abstract

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 equations, and then transfer functions are used to calculate the appropriate controller coefficients. The proposed control scheme is designed and its performance is evaluated using Matlab/Simulink.
