A new feedback-linearization-based neural network (NN) adaptive control is proposed for unknown nonaffine nonlinear discrete-time systems. An equivalent model in afflne-like form is first derived for the original nonaffine discrete-time systems as feedback linearization methods cannot be implemented for such systems. Then, feedback linearization adaptive(More)
The driver controlling model of car-following based on preview follower theory is advanced by analyzing the relation of direction controlling and velocity controlling on the following car and regarding the whole car-following course as preview-follow to the velocity of the leading car for n times. The model could describe the car-following behaviors more(More)
The different car-following indexes in different traffic flow states are extracted first. And then a model is advanced to imitate the whole course from collecting information, making decisions to controlling the states of vehicles by using a new method named Information Fusion. One neuron is set, as a perception, in order to show the car-following behavior(More)
During the gasoline engine transient process, both fuel quantity and fuel film parameter change, fuel film dynamics balance in intake pipe is destroyed, which makes the fuel quantity from nozzle and fuel quantity into the cylinder not be equaled. Therefore, fuel film model need to be established accurately in order to control the air fuel ratio accurately.(More)
Because the oxygen sensor is installed into the vent-pipe of gasoline engine, the air fuel ratio signal of gasoline engine exists transmission delay, which affects the control accuracy of air fuel ratio if using directive air fuel ratio sensor signal. To overcome air fuel ratio transmission delay affection, a new air fuel ratio predictive control method was(More)
During the gasoline engine start process, air fuel ratio of gasoline engine always greatly departs the theoretical air fuel ratio by the affection of intake pipe fuel film. To decrease exhaust emission in engine start process, the dynamic characteristic of intake pipe fuel film is analyzed; a new dynamic fuel film model of intake pipe based on Aquino model(More)
During the gasoline engine start process, both fuel quantity and fuel film parameter change, fuel film dynamics in intake pipe is not balance, which makes the fuel quantity from nozzle and fuel quantity into the cylinder not be equaled. In order to control the air fuel ratio accurately in gasoline engine start process, fuel film model of intake pipe need to(More)
