On the firing angles control of a 8/6 switched reluctance machine

This paper deals with the influence of the firing angles on the electromagnetic torque and losses of a four-phase switched reluctance machine. Three indicators are considered for evaluating these quantities in three situations. First case scenario consists in the variation of the turn-on and turn-off angle for a fixed dwell angle. In the second and third studies the turn-on and turn-off angle are alternatively fixed and the evolution of the key performance indicators with the current and speed are investigated. The utility of this work is related to the fact that most of the specialized minimization routines are strongly influenced by the choice of the initial points. A procedure for the computation of such points is suggested in the paper.SCOPUS: ar.j
