基于S7－400PLC的SMPT－1000压力流量控制策略设计

摘要

This paper uses SMPT-1000 ( Super Multifunction Process Control Training System ) to simulate the real boiler , and studies the problem of its outlet steam pressure and flow control strategy design .Based on Siemens S7-400 PLC and PCS7 pro-gramming software , by using SCL language fuzzy-PID controller , it shows that the outlet steam pressure and flow can be controlled in the scope of industrial requirements .%用SMPT－1000（高级多功能过程控制实训系统）来模拟真实的锅炉，研究其出口蒸汽压力、流量控制策略设计问题。基于西门子S7－400 PLC和PCS7编程软件，利用SCL语言编写了模糊－PID控制器，控制出口蒸汽压力和流量控制在工业要求的范围之内。
