本論文主要在探討永磁式同步馬達驅動電路死區時間效應及其補償方法。論文中吾人建立了驅動電路死區時間的數學模型,並利用MATLAB進行死區時間數學模型之模擬,再透過實測結果來對照死區時間數學模型是否吻合,其結果顯示數學模型具有相當大的不確定性。此外吾人研究及實現了多種死區時間補償方法並計算各種補償方法之總諧波失真(total harmonic distortion, THD)以驗證其補償之成效。在實作上,本系統使用德州儀器公司(Texas Instruments, TI)所生產的數位信號處理器做為控制核心以實現馬達驅動電路之死區時間補償。藉由實作結果得知,在眾補償方法中,以d-q軸電流PI控制加入建表前饋補償有較佳的補償效果。
This thesis studies methods of the dead-time compensation for permanent magnet synchronous motor drivers. In this thesis several dead-time compensation methods are implemented and tested on motor drivers. The total harmonic distortion is used to evaluate the compensation performance. In experiments, the compensation algorithms are implemented through a digital signal processor produced by the Texas Instruments. Furthermore, effectiveness of the dead-time compensation methods is verified through experiments. It is shown that PI control with feedforward compensation has better performance.
