摘　　要：磁悬浮球系统是一个实时控制系统,利用参数易于修改和代码便于工程应用特点的NI LabVIEW平台,对磁悬浮球系统的比例-积分-微分(PID)控制算法进行仿真。本文为系统设计了模拟PID控制算法、变参数PID控制算法;同时为了能获得更好的控制性能以及更多先进算法的支持,利用组件对象模型(COM)技术引入MATLAB与LabVIEW无缝集成,成功设计了基本模糊控制和模糊PID控制算法。仿真结果表明,模糊PID控制算法能更好的实现对磁悬浮球系统的控制;同时,COM技术的应用使得LabVIEW程序得到MATLAB强大的算法支持,大大缩短程序编写时间、显著提高应用程序的性能、并使得算法更易于实际工程应用。Magnetic levitation ball system is a run-time control system,using NI LabVIEW which a software platform with the features of modifing the parameters easily and applicating the codes conveniently,to simulate the PID control algorithm of magnetic levitation ball system.In this paper,for the magnetic levitation ball system we designed analog PID control algorithm and variable parameter PID control algorithm;at the same time,in order to achieve better control performance and more supports of advanced algorthm,we intergrate MATLAB and LabVIEW seamlessly by COM technology.Then we successfully designed algorithms of basic fuzzy control and fuzzy PID control.The results of simulation show that the fuzzy PID control is the best of four control algorithms to apply to the control of magnetic levitation ball system;and with the COM technology,the LabVIEW program can get more powerful algorithm supports from MATLAB,this application cuts more time of programming,improves the performance of program significantly and makes algorithm easily applied to practical engineering.
