隨著科學(xué)技術(shù)的發(fā)展,人們在開發(fā)和利用陸地資源的基礎(chǔ)上,將目光投向了占地球面積71%的海洋。作為探索海洋的重要工具,水下仿生機(jī)器魚成為研究的熱點(diǎn)之一,科研工作者在機(jī)器魚的仿生推進(jìn)機(jī)構(gòu)設(shè)計、運(yùn)動控制、水動力學(xué)分析等方面做了大量工作。根據(jù)推進(jìn)方式的不同,機(jī)器魚可分為身體/尾鰭推進(jìn)方式(Body and/or Caudal fin Propulsion mode,BCF)和中央鰭/對鰭推進(jìn)方式(Media and/or Paired fin Propulsion mode,MPF)。其中,針對機(jī)器魚的基本游動行為控制問題,已經(jīng)取得了較多的結(jié)果。本文針對動態(tài)水環(huán)境中自主仿生機(jī)器魚的運(yùn)動控制問題展開研究,以提升其在復(fù)雜水環(huán)境中完成任務(wù)的能力。主要工作內(nèi)容如下:1.系統(tǒng)總結(jié)了仿生機(jī)器魚的研究進(jìn)展。針對魚類游動機(jī)理、仿生推進(jìn)機(jī)構(gòu)設(shè)計、運(yùn)動控制技術(shù)、能源供給和水下通信技術(shù)等內(nèi)容,系統(tǒng)分析了機(jī)器魚領(lǐng)域的研究進(jìn)展和存在的主要問題,在此基礎(chǔ)上,從工程應(yīng)用和性能提升兩個方面,討論了機(jī)器魚領(lǐng)域未來的研究方向和發(fā)展趨勢。2.基于中樞模式發(fā)生器(Central Pattern Generator,CPG)模型,設(shè)計了...
