基于免疫原理的蟻群算法及其在熱工控制系統(tǒng)中的應(yīng)用.pdf

1、摘要本文針對(duì)基本蟻群算法在尋優(yōu)過(guò)程中容易出現(xiàn)停滯現(xiàn)象的問(wèn)題，提出在該算法中引入免疫機(jī)制，將待求解問(wèn)題看作抗原，而問(wèn)題的解看作抗體，通過(guò)基于濃度的選擇機(jī)制和多樣性保持策略來(lái)提高蟻群算法的全局搜索能力和避免停滯現(xiàn)象。仿真研究表明，此算法極大地提高了搜索能力和避免了停滯現(xiàn)象.最后，本文研究了該算法在熱工控制系統(tǒng)過(guò)程辨識(shí)和控制器參數(shù)優(yōu)化問(wèn)題上的應(yīng)用。關(guān)鍵詞:蟻群算法，免疫疫苗，過(guò)程辨識(shí)，參數(shù)優(yōu)化ABSTRACTInordertosolvebas
