Closed-loop dynamic response of a static Scherbius drive

Abstract

Generalized root-loci techniques, developed in the mid-70's for squirrel cage motors, have been extended to wound rotor, slip energy recovery systems (static Scherbius drive). In this paper, the influence of a feedback control loop on these root-loci is considered. General conclusions on Scherbius drive dynamics as well as some experimental verifications are also included.
