基於干擾扭力估測之直流無刷馬達穩速控制

BLDC Speed Regulation Base on Disturbance Torque Estimation

指導教授 : 林繼耀

摘要


本論文基於干擾扭矩估測,用以補償因負荷改變所造成的轉速誤差。在穩速系統中,通過使用估測器和串級控制 $PI-PD$ 來處理這些問題。在此系統分為兩個部分,一個是補償干擾扭矩,另一個是速度控制。 干擾扭矩估測是由擴增型估測器加上一個扭矩計算器,而干擾扭矩補償則是使用 $PI-PD$ 控制器來作為補償的控制,其兩個控制器採串級反饋補償的形式:內環$PD$ 通過控制電流追蹤來補償干擾扭矩,而外環 $PI$則是通過轉速追蹤來補償速度誤差。 最後通過模擬來確認設計之可行性,並於本文末呈現實驗結果。

並列摘要


We consider a speed regulation problem under varying load by using an observer and cascade PI-PD controllers for this problem. This research discusses the use of disturbance-torque estimation and PD control to compensated for the disturbance torque. Disturbance-torque estimation is performed by an augmented observer followed by a torque calculator. The controller has the form of cascade feedback compensation: the inner loop PD control to compensate for the disturbance torque, and the outer loop PI control to compensate for the speed error. The purpose of this study is to quickly compensate speed error when disturbance torque substantially changes.
