摘要
工业控制中,通过PLC梯形图语言来实现复杂的控制算法比较困难,并且常见PLC内部存储器容量较小,制约了先进控制算法在PLC上的应用。结合Matlab强大的计算能力和灵活的编程设计,设计基于OPC(OLE for Process Control)通讯技术的Matlab7.0与PLC的控制平台,可方便实现先进控制算法在PLC上的应用。使用该控制平台,Matlab实施模糊自适应PID控制算法,B&R PLC进行实时数据采样和输出,实现了对温度对象的控制,取得了良好的控制效果。
A control platform consisting of Matlab7.0 and B&R PLC is developed based on OPC technology.This platform takes advantage of the Matlab's abilities of strong computing and the flexible programming design.Through this platform,advanced control algorithms can be easily accomplished in PLC.A control strategy,which uses Matlab to carry out fuzzy adaptive PID algorithm,and accomplishes real-time data acquisition and output by B&R PLC,is applied to the temperature control of actual temperature device.
