摘要
对单自由度磁悬浮系统进行研究是研究磁悬浮技术的一个有效方法。根据磁力轴承基础理论建立单自由度磁悬浮球系统模型,在MATLAB/SIMULINK环境下进行控制仿真分析,设计MATLAB实时控制器,利用可视化操作界面和实时监控调试程序来整定PID参数,并采用变参数PID控制方法实现了磁悬浮球系统的实时控制,使球在4 s内达到±0.01 mm精度的稳定悬浮状态。
Researching on magnetic bearing system with single degree of freedom is an effective way to study magnetic bearing technology. A system model for magnetic levitation ball was established based on magnetic bearings foundation theory. This paper took a control simulink analyst with MATLAB/SIMULINK, designed MATLAB real-time controller, turned PID parameters with visual operating interface and real-time monitor debugging program, and employed variable parameter PID control method, it realized the real-time control of magnetic levitation ball. And the ball was suspended steadily in the range of ±0.01 mm within 4 seconds.
