汽車電子技術(shù)隨著汽車保有量的不斷增多，導(dǎo)致石油能源消耗的急劇增加，引起能源枯竭，油價(jià)上揚(yáng)。 variable structure slidingmode control。關(guān)鍵詞 電子節(jié)氣門，電控系統(tǒng)，變結(jié)構(gòu)滑模，控制算法，硬件系統(tǒng)AbstractAuto electronic control has made rapid progress by more requirements of the society, pending tougher emission standards and the developments in electronics, and DrivebyWire is one of the most important technologies. ETCS (electronic throttle control system) is one part of the powertrain control system, it plays a very importantrole in powertxain control. This thesis firstly introduced the ETCS, then modeled and simulated its dynamics and electrics
