    Abstract: 本篇論文主要為介紹磁浮球定位控制系統,在論文中建構整體的系統為非常之重要,其中包括感測系統,它的功能為感測磁球之位置;控制器目的為控制磁球之位置;電磁鐵驅動系統,利用電流來驅動電磁鐵以產生電磁力;訊號擷取系統,將位置電壓訊號擷取自電腦端,可藉由電腦端來即時分析其訊號,每一系統都有各自的重要性,缺一不可。 論文中,控制器的設計包含數位控制器方面以及類比控制器方面。在數位控制器方面必須要有高速的A/D和D/A的轉換速度,因為控制器的響應必須相當快速即時控制磁球位置。在類比控制器方面,以一些被動性元件來實現控制器,如電阻、電容以及運算放大器等等。此外,以RS232傳輸介面來顯示出磁球之位置與狀態,並且可藉由這些資料來達成即時控制的目的。 In this research, we are concerned with the control for the magnetic levitating systems. Also, we complete the implementation of the whole magnetic levitation control system. It’s composed of the sensor system that is used to detect the ball’s position, the controller that can control the ball’s position, and the driver outputs the current to drive the electromagnetic coil which generates the magnetic force, and the signal acquisition system that converts the voltage signal to the digital signal to be analyzed by the computer in real time. In this thesis, the design of the controller includes digital controller and analog controller. The digital controller must be implemented by high speed A/D and D/A converter to control the ball’s position. The part of the analog controller can be implemented by some passive components, such as resistor, capacitance and operational amplifiers. In addition, we utilize the RS232 communication interface to display the ball’s position and the state.
