44、。由于發(fā)動機(jī)動態(tài)性能滯后和離合器模型的時變特征,建立完全精確的動力學(xué)模型十分困難,而且由于車輛起步時載荷、擋位等變化,使離合器傳動系中參數(shù)具有不確定性,限制了最優(yōu)控制的性能。</p><p> 模型參考自適應(yīng)控制策略,可自動適應(yīng)離合器狀態(tài)、地面條件以及發(fā)動機(jī)的變化,確保沖擊度和滑磨功處于合理的范圍。但對于非線性時變的自適應(yīng)控制系統(tǒng)而言,系統(tǒng)的穩(wěn)定性、魯棒性等方面的理論尚不完善不易建立性能較好的自適應(yīng)控制系統(tǒng)。&

48、獲取優(yōu)秀駕駛員的換擋規(guī)律。HAYASHI等利用模糊控制和神經(jīng)網(wǎng)絡(luò)方法,對優(yōu)秀駕駛員的換擋規(guī)律進(jìn)行辨識,建立了基于經(jīng)驗的換擋規(guī)律,提高了車輛在爬坡及制動工況時的性能。實際工程應(yīng)用方面,三菱汽車公司率先應(yīng)用神經(jīng)網(wǎng)絡(luò)邏輯電路,成功開發(fā)了能最優(yōu)選擇變速擋位的INVECSⅡ型軟件系統(tǒng)。第二種為基于約束條件的換擋規(guī)律,也可稱為傳統(tǒng)的換擋規(guī)律,通常是基于發(fā)動機(jī)試驗數(shù)據(jù),利用回歸分析、插值法、神經(jīng)網(wǎng)絡(luò)等系統(tǒng)辨識方法,建立發(fā)動機(jī)的模型。然后在動力性和經(jīng)濟(jì)
