1、武漢理工大學(xué)碩士學(xué)位論文并聯(lián)式混合動(dòng)力電動(dòng)汽車的模糊邏輯控制姓名:邱海漩申請(qǐng)學(xué)位級(jí)別:碩士專業(yè):車輛工程指導(dǎo)教師:楊萬福2003.2.1武漢理工大學(xué)碩士學(xué)位論文摘要本文首先分析了混合動(dòng)力電動(dòng)汽車的混合驅(qū)動(dòng)結(jié)構(gòu)和類型,并對(duì)各種驅(qū)動(dòng)類型的特點(diǎn)和適用條件作了總結(jié)。接著闡述了并聯(lián)式混合動(dòng)力電動(dòng)汽車的控制思想和控制策略,并對(duì)不同的控制策略進(jìn)行了對(duì)比,確定以模糊邏輯控制為基礎(chǔ)的控制策略。然后簡(jiǎn)單介紹了模糊理論的基礎(chǔ)知識(shí),最后建立了適用于并聯(lián)混合動(dòng)力車輛的系統(tǒng)模型,對(duì)混合動(dòng)力車輛在起步、加速、巡航、減速、怠速
2、不同運(yùn)行模式下的能量流進(jìn)行了分析,提出了針對(duì)并聯(lián)混合動(dòng)力車輛在不同運(yùn)行模式下的變結(jié)構(gòu)模糊控制策略^慪種控制器實(shí)際上是一種多結(jié)構(gòu)的模糊控制器,以此來適應(yīng)在汽車各個(gè)模式下的能量流的知識(shí)庫(kù),根據(jù)整個(gè)能量管理策略提出了汽車在不同運(yùn)行模式下的控制規(guī)則集,該能量管理策略采用高效率圖來分析部件,蓄電池狀態(tài)保持一定水平,換擋點(diǎn)在優(yōu)化范圍。通過對(duì)混合動(dòng)力車輛的不同控制策略在NEDC循環(huán)工況下的計(jì)算機(jī)仿真和結(jié)果分析,結(jié)果表明,采用變結(jié)構(gòu)模糊控制策略的混合動(dòng)力車輛在不改變汽車的性能和電池SOC狀態(tài)的情況下,經(jīng)濟(jì)性有所
