Abstract :
A self-tuning algorithm is proposed for the control of the air-fuel ratio in internal combustion engines. Such a controller can overcome problems connected with unknown bias of the engine dynamics, slowly varying engine parameters and excess oxygen sensor characteristics. The simulation study has focused on near-steady-state situations and shows the feasibility of self-tuners in comparison with conventional PI controllers.
