本論文探討智慧型高效能電風扇的設計研發，其目的在於使室內空間對流風的有效利用，創造較佳的舒適涼風生活空間品質。研究內容包含以高效率永磁同步電動機作為電風扇馬達的控制策略研究，及其在智慧型自動熱源追蹤系統之適應應用，技術研發部份包括多段對流風控制及智慧型多目標人員自動追蹤系統兩大主軸，風扇系統之外型、旋轉葉片設計有別於傳統，以環形陣列式及噴射機渦流葉片之外型為設計參考，並運用3D列印技術製作而成。
多段對流風控制系統可追隨設定指令而控制風扇運轉性能，轉速調控範圍設計在900 rpm至1,400 rpm間，以100 rpm為一組實驗級距，共分為六段區間，並以實驗結果驗證其穩定性，精準度約為99%。智慧型多目標人員自動追蹤系統，偵測範圍為0度至180度，實驗分為四種量測：全區域、左半區域、右半區域及零區域人員偵測，並將偵測之溫度數值傳至數據庫，由監控視窗隨時更新數據，並利用人員位置用演算結果自動控制出風口之角度，使空間內每一位人員均可同時分配得幾乎同等風量與舒適感。
本論文系統以數位信號處理TMS320F28335為主要控制核心，搭配周邊硬體：微控制器、自動追蹤電路、霍爾感測器信號電路、紅外線溫度感測器及三相變頻器等；並藉由永磁同步電動機結構、數學模型及座標軸轉換，採用轉速閉迴路設計控制器，設計電壓空間向量脈波寬度調變策略，以C語言完成程式撰寫，完成整套驅動控制系統。

This thesis is developing an innovative smart electric fan to create comfortable indoor living environment. The study included high performance control strategy of permanent magnet synchronous motor and its application to intelligent automatic tracking system. The research can be divided into two main categories, speed control strategy for multi-stage air flow control and automatic heat source tracking system to provide smart tracking multi-target person. The innovative electric fan appearance and blade are, quite different from the traditional model, constituted by ring matrix array of multi-fan units and the jet vortex blades referred, which were made with 3D printing technology.
The multi-stage air flow control system can effectively control the running performance of the fan. The control range is between 900 rpm to 1,400 rpm, and being divided into six sections with 100 rpm apart from each other. The stability and operation error, the accuracy is about 99%. The smart multi-target tracking system can scan and detect person positions from 0o to 180o range and updated the person position/temperature in the database at all times. The scanning space is divided into four areas, full area, left half area, right half area, and zero area for personnel detection. The person position is used to automatically control the direction of the air flow outlet with the calculation results.
The system takes a digital signal processing unit TMS320F28335 as the main control component, deployed with peripheral hardware including microcontroller, automatic tracking circuit, Hall sensor detection circuit, infrared temperature sensor and three-phase inverter, etc. The mathematical model of permanent magnet synchronous motor was formulated, relative manipulations included coordinate axis conversion, the closed-loop speed control scheme, voltage space vector pulse width modulation technique etc. are systematically together to complete the entire drive control system via the program writing in C-language.
