摘要
以2 000 t/d新型干法水泥分解炉为研究对象,使用前馈-负反馈的多变量模糊控制方法,实现了分解炉出口温度的控制。建立了水泥分解炉出口温度数学模型(MISO),使用VC++6.0对水泥分解炉出口温度多变量模糊控制与常规的PID进行仿真对比研究。研究结果表明:前馈-负反馈的多变量模糊控制效果优于传统PID控制。为便于工程实现,采用西门子WinCC6.0为OPC服务器端,自行开发的分解炉出口温度VC多变量模糊控制软件为OPC客户端,通过OPC接口成功地实现了二者间的数据通信,且系统运行稳定、效果良好,具有很强的实际应用意义。
Technically, the cement decomposing furnace is a typical nonlinearity, strong coupling and complexity control object. It＇s difficult to .establish a precise mathematical model. A feed-feedback multivariable fuzzy control strategy for better controlling outlet tem- perature of decomposing furnace on a new dry process cement 2000 t/d clinker production line is adopted. In order to verify the feasibility of its control strategy, the simulation results of multivariable fuzzy control and PID are compared based on a dynamic outlet temperature model of decomposing furnace. The research result shows that the effect of the feed-feedback muhivariable fuzzy control is better than the traditional PID. The Siemens WinCC6. 0 is used as OPC server and the multivariable fuzzy control software developed with VC ＋ ＋ is used as OPC client . Data communication is realized successfully by OPC interface. The system running is steady and its effect is good. The research result shows some value in application and promotion.
