Abstract

This paper deals with the control problem of an engine air path system with low pressure exhaust gas recirculation (EGR). The considered air path system with low EGR can be modelled as a system with time-delays due to the transport delay of gas flow from EGR. It results in over intake fresh air, and thus it causes torque overshoot. An output predictive control system is designed for a time delay air path system in order to obtain the desired fresh air mass flow. In the considered system, the intake fresh air mass flow and the EGR rate are taken as the outputs, and the throttle valve and the EGR valve are considered as inputs of the system in this paper. A detailed air path system model with time-delay will also be derived for confirming the effectiveness of the proposed method through numerical simulations.
