摘要
为了更好地研究磁悬浮技术,根据电磁学理论,对磁悬浮球控制系统的原理进行了分析,建立了控制系统的数学模型,进行了控制系统的稳定性分析;针对磁悬浮球控制系统的滞后特性,提出了PD超前补偿控制方法,组成了闭环反馈控制系统,并在MAT-LAB下进行了控制系统的软件仿真;在此基础上,根据电子学和自动控制理论,设计了一个基于PD控制器的磁悬浮球控制系统,实现了钢球的稳定悬浮;控制系统的电路部分完全由模拟电子电路实现,既简单又实用。
In order to research the maglev technique well, the principle of a maglev ball control system is analyzed, including deducing its math model and analyzing its stability. Aiming at the lag characteristic of the control system, a PD lead compensation control method is advanced to compose a dosed loop feedback control system, which is simulated by using the MATLAB. Then on the basis of electronics and automation theories, a maglev ball control system based on PD controller is designed which can suspend a steel ball stably. The circuit of the control system is achieved by analog circuit completely, which is simple and practical.
