| Summary: | 碩士 === 國立臺灣科技大學 === 電機工程系 === 99 === This thesis proposes the design and implementation of a sensorless PMSM drive system for three-phase fan motors. The permanent magnet synchronous motor and the space-vector pulse-width-modulation strategy are discussed first.
Two different control methods, including phase control algorithm and reactive power control algorithm are proposed next to improve the efficiency of the PMSM and obtain a closed-loop speed control system. The starting technique is investigated as well.
A digital signal processor, TMS320LF2407, is used as the control kernel to execute the control algorithms. As a result, the hardware circuit is very simple. Several experimental results are shown to validate the feasibility and correctness of the proposed method.
