The dynamic testing method 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 compared to traditional methods. Within this work, a performance evaluation of the dynamic testing method applied to the synchronous reluctance machine is presented. This paper discusses the challenges of a dynamic test of a nonlinear synchronous machine and suggests a Fuzzy PD+I controller for improved control performance and measurements. Finally, the dynamic testing method measurements are compared to results of the constant speed method. The constant speed method measurements of flux-linkage and torque curves confirm the validity of the dynamic testing method measurements for this machine.
