A review of control methods for brushless doubly-fed reluctance machines

This paper considers various aspects of field oriented control, direct torque control and scalar control of an ideal brushless doubly-fed reluctance machine (no saturation and with sinusoidally distributed windings). Modeling fundamentals are introduced first and mathematical expressions of interest to the primary flux oriented control for the machine are subsequently derived from the model equations. A vector control algorithm based on these expressions is then briefly discussed.
