Dynamic Testing Characterization of a Synchronous Reluctance Machine

The dynamic testing method (DTM) has been shown to accurately characterize the electromagnetic model of permanent magnet synchronous machines by describing the relationship between the phase currents and the linked magnetic flux with minimal amount of test equipment as compared with traditional methods. Within this paper, a performance evaluation of the DTM applied to a synchronous reluctance machine is presented. This paper discusses the challenges of a dynamic test of a nonlinear synchronous machine and suggests a fuzzy proportional, derivative and integral controller (PD + I) controller for improved control performance and measurements. Finally, the DTM measurements are compared with the results of the constant speed method (CSM). The CSM measurements of flux linkage and torque curves confirm the validity of the DTM measurements for this machine.
