隨著人口的快速增長和能源的急劇消耗,節(jié)能環(huán)保變得越來越重要。在此背景下,人們對汽車發(fā)動機(jī)系統(tǒng)在燃料效率和低排放方面的性能有了更高的要求。電子節(jié)氣門（Electronic throttle,ET）系統(tǒng)在實(shí)現(xiàn)這一目標(biāo)中發(fā)揮著重要作用。它通過控制進(jìn)入系統(tǒng)發(fā)動機(jī)的空氣流量來控制空氣-燃料混合比,能有效減少環(huán)境污染和優(yōu)化燃料消耗。電子節(jié)氣門系統(tǒng)由節(jié)流閥本體、傳感器、齒輪組和控制節(jié)氣門閥板開度的直流電機(jī)等部件組成。電子節(jié)氣門系統(tǒng)是一個耦合非線性系統(tǒng),其模型近似于一個真實(shí)系統(tǒng),它的未建模動態(tài)問題常常被忽視。傳統(tǒng)的線性控制方法很難滿足電子節(jié)流閥系統(tǒng)的控制需求,因此本文為提高電子節(jié)氣門系統(tǒng)的閉環(huán)性能,提出了一種高階滑模控制方案。本文的貢獻(xiàn)主要體現(xiàn)在以下幾個方面:本文考慮了ET系統(tǒng)的控制問題,并提出了一種高階滑模控制方案。ET系統(tǒng)是一個非線性系統(tǒng),其模型是實(shí)際系統(tǒng)的近似值,所以存在未建模動態(tài)。因此,ET系統(tǒng)的一般性能通常受非線性,未建模動態(tài),外部干擾參數(shù)變化的影響。下面將分別闡述本文重點(diǎn)。首先,本文利用高階滑�？刂品椒▉砀纳艵T系統(tǒng)的閉環(huán)性能。高階滑�？刂撇粌H保留了傳統(tǒng)滑模控制的主要優(yōu)點(diǎn),而且可以用來減少...
