摘要：设计了双容水箱实验对象,该对象具有时变、纯滞后和不确定性等复杂特性,可以满足从对象特性测试到串级控制、预测控制等多层次过程控制实验教学要求。为该对象设计和开发了测控系统,可以实现基于智能仪表的控制、基于PLC的控制和同时利用智能仪表与PLC的控制方案。实验系统测控软件采用组态软件开发,利用OPC技术开发了独立应用程序从实验系统软件提取实时实验数据。应用表明,该系统具有功能灵活完善、配置合理、实验成本低廉等优点,很好地满足了过程控制实验教学要求。
A two water tanks process was designed.The system is characterized by time varying,dead time and uncertainty,which meets the experimental requirements from process black-box modeling to cascade control and predictive control.Several different control systems using intelligent instruments,programmable controller or both of them were developed.The measurement and control software for the experimental system was developed using configuration software.An application software was developed to extract real-time data from the measurement and control application software with OPC technology.Applications have shown that the whole system is flexible for its multiple functions,reasonable in configuration,cost effective in running.It meets the experimental requirements for process control related courses.
