無人機馬達幅值調變低取樣頻率之無感測器適應性控制開發

Low Sampling Frequency Sensorless Drone Motor with Adaptive Control and PAM Drive

摘要


本論文研究無人機之驅動策略並且提出新的幅值調變驅動方式,主要分為三部分:一為解決無人機所用之直流無刷馬達運作頻率接近微控制器之運算頻率時因為取樣頻率不足所導致的問題,二為利用適應性控制提升無人機速度迴路的響應。三為利用新的SiC寬能隙半導體製作PAM的前級驅動以提升效率並且縮小整體的重量以及體積。

This article discusses development of drone control strategies and proposes new drive methods, these methods mainly consist of three parts: 1. to solve problems caused by low sampling rate when the operating frequency of BLDC is near to that of the micro-processor; 2. to use adaptive control to enhance the response of the drone's control loop; and 3. to use wide band gap semiconductor, namely SiC, to increase total efficiency and reduce total size and weight.
