15、重型卡車。汽車的速度決定了它們的動態(tài)模型, 動擺頻率應(yīng)該被精確獲取兩個旋慣量被一個泵彈性的連接起來。Alexander和Loukianov 建立了一個健全的穩(wěn)定的控制體系,用于控制內(nèi)燃機和雙缸結(jié)構(gòu)的發(fā)動機。環(huán)滑模式控制方法被使用在驅(qū)動器循環(huán)提供快速并且精確跟蹤節(jié)流孔。一個可適應(yīng)的控制結(jié)構(gòu)被調(diào)在其他汽車在通行條件下,緩慢的適應(yīng)并且敏感性基于梯度算法PI 管理器,結(jié)果被調(diào)整為一份二次方函數(shù)。Martin Sommer ville提出一份氣動

17、控制。 由于一些作用被生成在這個階段,譬如扭轉(zhuǎn)力振動使傳動器的速度差額增加,直線動擺增加。小卡車共振磁通常是在1 0 赫茲到20 赫茲之內(nèi)的范圍的柴油引擎。另外相當數(shù)量能量被轉(zhuǎn)化為熱與滑行階段時間是按比例在范圍為0.5秒到2.0秒內(nèi)變化。 </p><p>  而且被重復(fù)應(yīng)用的負荷作用生成表面磨損, 減少傳動器摩擦板的壽命。圖4 說明可變參數(shù)的傳動器滑行階段,傳動器扭矩增量取決于應(yīng)用的夾緊力,當它到達最大值時鎖定

18、引擎和傳動器速度與熱能增量取決于扭矩和滑動速度的點 研究員的控制方法導致沖擊,例如表面磨損,小摩擦損耗,在滑行時引擎制動的最小時需求。這些都將引起不期望的線性磨損。</p><p>  動態(tài)模型由Centea開發(fā),并且學習滑動差異的作用和摩擦系數(shù)。結(jié)果期間表明,摩擦正梯度系數(shù)各種各樣的摩擦材料所影響。滑動速度提供一個更好的阻止作用和少許摩擦。</p><p>  佛朗哥和Luigi

19、 開發(fā)了公式化的滑動控制技術(shù)如同一個線性時間不變的設(shè)計。傳動器根據(jù)閉合回路以反饋控制。目前,模糊邏輯控制有分析傳動器動態(tài)回應(yīng)特性在滑行階段的特性。AMT 標準是一個最重大的因素,有對穩(wěn)定狀態(tài)影響的震動發(fā)生,當插入目標齒輪轉(zhuǎn)入驅(qū)動器。在傳動齒輪之間無法順利地完成歸結(jié)于速度的不同。</p><p>  標準是汽車的惡化驅(qū)動損失由熱量形式被散發(fā)。驅(qū)動軸轉(zhuǎn)動扭矩在齒輪期間主要介入在震動中。齒輪對引擎的震動由于慣性扭矩,由

20、速度改變而成,并且這個進程扭矩是重大的,并且更加中意改進震動的扭矩。是首要執(zhí)行的,是對駕駛性能的一個重要限制如果不被阻止。此控制策略提供齒輪嚙合的優(yōu)化時間,尤其是超載駕駛后上坡時。一個州控制技術(shù)被kazumi和yasunori提出,它可以不需要連接傳感器便可以檢測路的坡度,無論上坡或下坡,然后選擇恰當?shù)臋n位。In Ref〔19〕,一個控制方式被介紹出來之前,要根據(jù)導航系統(tǒng)所獲得的路面數(shù)據(jù),和精確的行駛速度,此速度齒輪的傳遞來實現(xiàn)。Min

21、owa所提出的方式是穩(wěn)定狀態(tài)的條件下,燃料消耗是引擎的速度和扭矩的影響,選擇合理的齒輪,提供最低的消耗率,因此要減小齒輪調(diào)速。</p><p>  5 AMT 控制未來進展</p><p>  AMT技術(shù)的潛能是要克服動力傳遞期間的扭矩的中斷問題,因為要提高系統(tǒng)的穩(wěn)定可靠性和加速度。2005年之后,AMT攜帶DCT技術(shù)控制時被期望很高的,年可以提高好的齒輪質(zhì)量和提高燃料的燃燒率,并降低價格

22、。AMT的將來設(shè)計集中在增加傳遞速度,使引擎操作趨于最佳運行軌跡,從而得到明顯的經(jīng)濟效益。另外,電路轉(zhuǎn)換技術(shù)的發(fā)展也將被加強重視。發(fā)達的電子控制儀器將被越來越廣泛的使用,例如空駛工程中的數(shù)字信號處理器,像在虛擬環(huán)境中迅速還原的可替代的儀器。而且也會有更多的建議會出現(xiàn),關(guān)于適應(yīng)邏輯控制軟件,其中包括車型和駕駛環(huán)境的識別。圖6所示為關(guān)于2005年運輸技術(shù)產(chǎn)業(yè)的預(yù)測數(shù)據(jù),也顯示了在6檔技術(shù)的AMT需求增加2.5個百分點的同時,5檔AMT的需求

23、下降了2.4個百分點。這要歸于速度比率范圍寬,節(jié)省燃料(5%—6%),減少熱量損耗和提速5%的優(yōu)勢。同樣的,5檔AT系統(tǒng)將隨著6檔AT的增加而減少。</p><p><b>  6 結(jié)論</b></p><p>  目前,AMT控制系統(tǒng)的硬件設(shè)備和軟件控制功能的數(shù)量持續(xù)增加,使AMT控制系統(tǒng)在國際化大環(huán)境中起越來越重要的作用。如今,AMT技術(shù)致力于機電運輸體系,而不是

24、液壓或氣壓體系。這種情況要歸終于低的基本成本和低的維修上。另外,電子驅(qū)動系統(tǒng)操縱簡單。AMT的控制政策的根本演變要依賴于現(xiàn)代控制理論的應(yīng)用,例如模糊邏輯,二次方優(yōu)化,離合器動態(tài)響應(yīng)的網(wǎng)絡(luò)神經(jīng)技術(shù),提高扭矩和齒輪運轉(zhuǎn)的效率高,消耗在電機響應(yīng)中的時間少等。所有這些有利因素使得AMT系統(tǒng)在運輸領(lǐng)域中占有舉足輕重的地位。</p><p><b>  附錄B</b></p><p&
