| Summary: | 碩士 === 國立臺灣科技大學 === 電機工程技術研究所 === 86 === This thesis presents the modeling and implementation of amicroprocessor MC 80196 based brushless motor drive system.Inorder to reduce the switching frequency, improve the inverterefficiency, and achieve a high performance drive system, a newbrushless drive is proposed here. Frist, a 25kHz, 4Kw resonantdc-link inverter has been constructed.Then, a simple method to reduce the switching frequency of the inverter has been investigated.Next, a high performance digital controller has been designed to obtain both good transient response and good load disturbance rejection capability of the whole system. Finally,the drive system has been implemented. Experimental results canvaildate the simulated waveforms. This thesis provides a newmethod to design and implement the brushless drive system.
