Evaluation of the constant current angle controlled reluctance synchronous machine drive

[摘要] ENGLISH ABSTRACT:This thesis describes. the design and evaluation of a constant current angle controllerfor a variable speed reluctance synchronous machine (RSM) drive, as an energyefficient high performance drive. An accurate model of the RSM, with the use offinite element analysis, is derived and implemented in simulation software. Thecurrent- and speed controllers are designed and evaluated using a complete simulationmodel of the whole drive. The controller is implemented on a TMS320F240 DSPbaseddigital controller, which was developed. The dynamic performance of theconstant-current-angle control is compared with that of the conventional constant-daxis-current control method. The results obtained from the RSM drive confirm thesimulation results. In the comparison of the two control methods it is shown that theconstant-current-angle controlled RSM drive is an energy-efficient drive with gooddynamic performance.
