Preview control of engine intake manifold pressure

This paper proposes a control design method for the intake manifold pressure of an internal combustion engine. It is based on a feedback controller that ensures the robustness to model uncertainties and a preview feedforward filter. The latter has an anticipating effect with respect to known future values of the reference signal, while at the same time taking into account the model dynamics and mitigating the control effort. The proposed approach is evaluated using the Matlab Simulink model of a spark ignition internal combustion engine in which parametric uncertainties and saturation are added. A nonlinear model predictive controller is implemented on the same model for comparison purposes.
