Abstract EN
A precise control of the normalized air to fuel ratio in spark ignition engines is an essential task.
To achieve this goal, in this work we take into consideration the time delay measurement presented by the universal exhaust gas oxygen sensor along with uncertainties in the volumetric efficiency.
For that purpose, observers are designed by means of a super-twisting sliding mode estimation scheme.
Also two control schemes based on a general nonlinear model and a similar nonlinear affine representation for the dynamics of the normalized air to fuel ratio were designed in this work by using the super-twisting sliding mode methodology.
Such dynamics depends on the control input, that is, the injected fuel mass flow, its time derivative, and its reciprocal.
The two latter terms are estimated by means of a robust sliding mode differentiator.
The observers and controllers are designed based on an isothermal mean value engine model.
Numeric and hardware in the loop simulations were carried out with such model, where parameters were taken from a real engine.
The obtained results show a good output tracking and rejection of disturbances when the engine is closed loop with proposed control methods.
