Abstract

This paper deals with air to fuel ratio control of a spark ignition engine, whose pollutant is a major cause of air pollution. A direct adaptive control using Gaussian neural networks is developed to compensate transient fueling dynamics and measurement error in mass air flow rate into the cylinder. The transient fueling compensation method is coupled with a dynamic sliding mode control technique that governs the steady state fueling rate. The proposed controller is simple enough for online computation and is implemented automotive engine using a PC-386
