本論文旨在發展兩種直流變頻壓縮機驅動器之無感測器技術，其一為高頻信號注入法結合換相信號轉速估測法之控制架構，其二為高頻信號注入法結合參考模型適應性控制法之控制架構。兩種控制架構皆以高頻信號注入法為啟動策略，藉此以達成壓縮機弦波啟動之功能，當壓縮機轉速爬升至所設定之轉速下，則系統將切換控制法則至適合應用於中高轉速下之無感測器控制法則，使壓縮機可以運轉至更高的轉速。另外本論文亦提出以智慧型類神經比例微分積分控制器取代傳統比例微分積分控制器來與高頻信號注入法進行結合，藉此進一步提升高頻信號注入法之估測性能。本論文首先介紹空調系統之運作原理，接著會針對高頻信號注入法、換相信號轉速估測法、參考模型適應性控制法，與類神經比例微分積分控制器等原理做詳盡的介紹。本文以PSIM模擬軟體與C語言所撰寫之動態連結檔模擬所提出之直流變頻壓縮機驅動系統控制性能，實作則以dsPIC 型號30F4011之微處理機控制所設計之直流變頻壓縮機驅動器，以驗證所提出架構之可行性。The objective of this thesis is to develop two kinds of sensorless DC inverter-fed compressor control scheme. One is the high frequency signal injection method combined with the commutation-signal-based speed estimate method, and the other is the high frequency signal injection method combined with the model reference adaptive control method. Both kinds of control structure use high frequency signal injection method for the start strategy to achieve sinusoidal starting. When the motor speed gradually increases to the preset speed, the driver will switch to the commutation-signal-based speed estimate method or the model reference adaptive control method to achieve higher speed control. Moreover, this thesis proposes PIDNN controller to replace the PI controller which is used in traditional high frequency signal injection method to improve the estimation ability for the rotor flux position. In this thesis, first, the operating principle of air-conditioning system will be discussed. Then, the theories of the high frequency signal injection method, the commutation-signal-based speed estimate method, the model reference adaptive control method, and the PIDNN controller will be introduced in detail. Furthermore, PSIM simulation with C language is used to simulate the developed control architecture. In addition, microprocessor-based Microchip dsPIC30F4011 is adopted to implement the sinusoidal DC inverter drive system to verify the feasibility of the proposed control scheme.
