在本文中,基于全局優(yōu)化的煙花算法(FWA),將現(xiàn)代計(jì)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(hào),誤差麥克風(fēng)用于采集殘差噪聲信號(hào),該信號(hào)同時(shí)也被控制算法使用。煙花算法是2010年提出的專門針對(duì)集群智能的算法,其最初靈感來(lái)源于煙花爆炸的概念�；�于ANC系統(tǒng),展現(xiàn)了煙花算法及其變體在系統(tǒng)識(shí)別領(lǐng)域的影響。使用進(jìn)化和計(jì)算啟發(fā)式范式算法設(shè)計(jì)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(lái)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(wú)需識(shí)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(shí),基于煙花算法ANC系統(tǒng)具有正弦噪聲信號(hào),隨機(jī)噪聲信號(hào)以及復(fù)雜隨機(jī)噪聲信號(hào)�；�于統(tǒng)計(jì)的觀察結(jié)果,通過(guò)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(jià)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(duì)具有精度,魯棒性和穩(wěn)定性的非線性ANC系統(tǒng),開(kāi)發(fā)了新穎的自然啟發(fā)煙花算法。推薦計(jì)算...
