A microcomputer control shceme for SRM drive using a novel power converter

摘要

This paper describes the scheme of 8098 microcomputer-based SRM control system. An improved power converter is involved in such a system, decreasing the requirements of hardware and making total system more reconomical. This close-loop SRM conrol system is developed for a four-phase machine, and include feedback control with speed loop and current loop. Sequence onctorl as well as synchronized angle control of SRM is both implemented using the 8098 single-chip processor, and conrol strategy can be changed conveniently with the load requirment by changing system 550W SRM prototype and performance were found to be satisfactory.
