碩士 === 國立雲林科技大學 === 電機工程技術研究所 === 86 === The synchronous reluctance motor(SRM) has the simple structure, easy controllability, no slip, and rotor without permanent magnets which has the advantages both of induction motor and brushless motor. Under the rising growth of power electron and powerful calculation of microprocessors, the AC motors have increasingly disentangled from the conventional analog controller, and develop toward the half-digital or full-digital controller. This thesis proposes a DSP based, variable speed system of synchronous reluctance motor. First, the construction, characteristics, mathematical model, and the nowaday control strategies of synchronous reluctance motor are studied. Second, a three phase inverter and their peripheral control circuit are finished. The space vector pulse width modulation method was applied. For improving the SRM low torque flaw, the maximum torque strategies was adopted. Finally, a quasilinear fuzzy control strategy is introdud to investigate the try and error spot of conventional speed controller and to improve transient response performance of whole closed system.
