HIGH-PERFORMANCE CONTROL OF SYNCHRONOUS RELUCTANCE MOTORS

Based on a (d,q) synchronous frame, the control problems of synchronou s reluctance motors are outlined. In particular, the effect of magneti c saturation, core loss, and angular measurement errors of various typ es are evidenced. A flux-observer-based control scheme, capable of ove rcoming most of the above problems, is proposed. The proposed control has been implemented on a prototype drive, adopting a 17-N.m 8000-r/mi n motor. The experimental results show quite a good performance, with particular emphasis on those applications which require a large consta nt-power speed range.
