模糊RBF 神經(jīng)網(wǎng)絡在鍋爐水位控制中的應用

水位控制是工業(yè)鍋爐控制系統(tǒng)中一個重要的環(huán)節(jié)，其控制質量的優(yōu)劣直接影響到鍋爐
的安全和經(jīng)濟效益。本文將一種基于模糊RBF 神經(jīng)網(wǎng)絡的PID 控制器應用與工業(yè)鍋爐水位的控制當中，它結合了傳統(tǒng)PID 以及神經(jīng)網(wǎng)絡和模糊控制的優(yōu)點，可以在線調整得到一組最優(yōu)的PID 控制參數(shù)。仿真結果表明這種控制器具有較好的適應性，控制效果得到明顯改善。

RBF Fuzzy Neural Network in Boiler’s Water Control Liu min Ma junshuang? Tangshan College,Tangshan 063000,China ) Abstract： The automated control of the steam package water level is a very important factor in industrial boiler production systems. The quality of the control will affect the safety and efficiency of the boiler. This article presents a controller which is based on Fuzzy Neural Networks and PID control in industrial boiler’s water level. This controller which combines the advantages of the Fuzzy control and Neutral Networks control can get the best PID parameters by self-adjustment on line. The simulation study proves that this control system has a better adaptability and can improve the control effect greatly.
