Electronic Throttle Control Strategy Develop

This paper researches on how to improve the ETB (Electronic Throttle Body) performance, as the emission requirement becomes more and more strict this core function’s performance becomes more and more important. We can get the command throttle position easy but there are many factors can affect the ETB intake air mass model in the real work environment, such as engine oscillation, intake air flow disturbance and motor aging and so on. We must build close loop control which should detect the condition change and correct plate open angle to improve the ETB work performance.
