基于神经网络的汽油HCCI发动机空燃比控制策略（Air/Fuel Ratio Control of Gasoline HCCI Engine Based on Neural Network）
汽油发动机 均质充量压缩燃烧 空燃比
2009/8/11
均质压缩燃烧（HCCI）在控制上存在难点，其中关键是基于循环的空燃比实时控制。HCCI汽油机没有能直接表征发动机每循环进气量的参数，因此，采用动态递归神经网络（Elman网络）预测HCCI发动机每循环的进气量。通过氧传感器闭环和瞬态工况中的油膜补偿，实现对HCCI发动机的稳态及瞬态工况下空燃比的精确控制。试验表明：汽油HCCI发动机神经网络预测模型及空燃比控制策略能满足HCCI发动机实时控制的需求...
