Dynamic Sliding Mode Control of Air-to-fuel ratio in Internal Combustion Engines Using the Hybrid Extended Kalman Filter
The large modeling uncertainties and the nonlinearities associated with air manifold and fuel injection in spark ignition(so engines has given rise to difficulties in the task of designing an adequate controller for air-tofuel ratio (AFR)control．Although sliding mode controI approaches has been suggested，the inescapable time-delay between control action and measurement update results jn chattering．This paper proposes the implementation of a nonlinear observer based control scheme incorporating the hybrid extended Kalman filter (HEKF)and the dynamic sliding mode control (DSMC)．The results established upon the proposed methodology are given which demonstrate superior performance in terms of reducing the chattering magnitude．
