摘要
设计了一个基于西门子S7-300PLC控制系统和双容水箱实验装置的混合实验平台,其涵盖了控制策略的仿真以及对实际对象的控制。该平台利用以太网和OPC通信,实现了控制器、被控对象及监测系统之间的数据互联传输,并以模糊Smith时滞补偿控制策略的应用验证为例,使得虚拟仿真和实际验证有机地融合在一起并能够灵活、快速地转换,提高了双容液位系统控制策略设计的可移植性,解决了系统设计和工程应用之间的脱节问题。
A mixed experimental platform based on Siemens S7-300 PLC control system and the experimental device for the double-capacity water tank is designed,which includes the simulation of the control strategy and the control of the actual object.By using the Ethernet and OPC communication,this platform realizes the data interconnection transmission between the controller,controlled object and monitoring system.Taking the application verification of fuzzy Smith time-delay compensation control strategy as an example,the virtual simulation and the practical verification can merge together organically and convert into each other flexibly and quickly,which improves the transportability of strategic designing for the double-capacity liquid level system control,and solves the disjointed problem between the system designing and engineering application.
