归一化模糊控制在换热器出口温度控制中的研究

Research of Normalization of Fuzzy Control in Heat Exchanger Outlet Temperature Control

换热器运行的好坏对整个生产很重要,可提高整个系统的运行性能,并节约能源。针对出口水温控制中,将传统的模糊控制的误差E和误差微分Ec采用归一化的方法处理,使误差E、误差微分Ec和输出增量ΔU在同一论域下。基于MATLAB环境下进行仿真,得到了实验结果。

The quality of heat exchanger is very important ,it can improve the operational performance of the entire system and save energy. For the outlet water control system , uses normalized method to treat the fuzzy control′s error E and differential error Ec ,makes the E ,Ec and ΔU in the same domain ,car-ries out simulation based on MATLAB environment and obtains the experimental results.
