本文以數位信號處理器(DSP)為控制核心,研製一套無速度感測元件驅動之電動車系統,系統包含了數位控制板、無刷直流馬達、充電器電路與電池組等。與傳統有感測元件驅動系統比較無載、瞬間加載以及加載起步之速度暫態響應,由實驗結果可得知本文所提出之無感測系統不論是在速度或電流響應方面均與傳統有感測驅動系統大同小異,特別是當系統達到穩定速度運轉時,無感測驅動系統之馬達相電流較有感測驅動系統明顯的小許多,證明本文所提出之無感測器驅動系統之正確性與可行性。在充電器方面,根據文獻探討,兩段式定電流定電壓充電法則被使用的較為廣泛且穩定,因此本文採用此法則,充電電路架構則使用順向式轉換器。
This thesis develops a sensorless driver of BLDC motors for the electric vehicles based on DSP controller. The system consists of a digital control board, brushless DC motor, charger circuit, and lead-acid batteries. Compared with traditional BLDC motor driver, it is found that sensorless driver exhibits similar performances with traditional sensor driver in terms of speed response and current response altogether. What is worthy of special notice is that, when operating at a very short time of start, the sensorless driver of BLDC motor produces an obviously smaller phase current than its sensor counterpart; this proves the correctness and practicability of the sensorless driver of BLDC motors. According to the literature on battery chargers, two-step constant current / constant voltage (CC/CV)rule is widely used and is relatively stable, which forms the reason of adopting this rule here. The charge circuit, on the other hand, is forward converter.
