本論文主要研究磁浮球控制系統。建構磁浮球控制系統包括感測單元,驅動單元與控制單元。在感測部份使用紅外線感測器。在驅動部份是使用脈波寬度調變的技術。在控制方面,分別使用類比式控制與數位控制兩種不同的架構。本論文所使用的控制方法為雙回路控制。內回路為電流控制而外回路則是位置穩定控制。所使用的控制器分別為PI及PD控制。
The main objective of the thesis is to investigate a magnetic levitation control system. A magnetic levitation control system includes a sensor module, a driver module and a control module. The couple of an infrared emitter and a receiver are used to detect the position of the ball. The PWM technique is adopted to implement the current driver. With respect to the control module, an analog controller and a digital controller are developed respectively. Two-loop control methodology is utilized for stabilization. The inner loop control subsystem is for a current driver and the outer loop control subsystem is for the ball stabilization.
