Abstract
Based on (d, q) synchronous frame, the control problems of synchronous reluctance motors are outlined. In particular, the effect of magnetic saturation, core loss and angular measurement errors of various type are evidenced. A flux-observer based control scheme is proposed, capable of overcoming most of the above problems. The proposed control has been implemented on a prototype drive, adopting a 17 Nm, 8,000 rpm motor. The experimental results show a quite good performance, with particular emphasis to those applications which require a large constant-power speed range.
