自然啟發(fā)煙花算法在非線性有源噪聲控制系統(tǒng)中的應(yīng)用
發(fā)布時間：2024-02-22 19:04
在本文中,基于全局優(yōu)化的煙花算法(FWA),將現(xiàn)代計算啟發(fā)式范式應(yīng)用于非線性有源噪聲控制系統(tǒng)(ANC)。參考麥克風(fēng)用于采集噪聲信號,誤差麥克風(fēng)用于采集殘差噪聲信號,該信號同時也被控制算法使用。煙花算法是2010年提出的專門針對集群智能的算法,其最初靈感來源于煙花爆炸的概念�；贏NC系統(tǒng),展現(xiàn)了煙花算法及其變體在系統(tǒng)識別領(lǐng)域的影響。使用進(jìn)化和計算啟發(fā)式范式算法設(shè)計基于ANC的控制器。該控制器用全局煙花算法搜索優(yōu)化的非線性Volterra濾波來表示。自然啟發(fā)煙花算法用于更新自適應(yīng)Volterra濾波器ANC系統(tǒng)的參數(shù),而無需識別次路模型。提出的均方誤差優(yōu)化概念用于最小化成本函數(shù)。將主/次路視為線性/非線性時,基于煙花算法ANC系統(tǒng)具有正弦噪聲信號,隨機(jī)噪聲信號以及復(fù)雜隨機(jī)噪聲信號�；诮y(tǒng)計的觀察結(jié)果,通過準(zhǔn)確性,復(fù)雜性以及收斂性分析證明了隨機(jī)求解器FWA的價值,即所提出的基于ANC控制器的優(yōu)化機(jī)制是有效,魯棒且穩(wěn)定的。此外,本文將所提出的算法與回溯搜索算法(BSA)和粒子群優(yōu)化算法(PSO)進(jìn)行了比較。針對具有精度,魯棒性和穩(wěn)定性的非線性ANC系統(tǒng),開發(fā)了新穎的自然啟發(fā)煙花算法。推薦計算...
