摘要：AbstractThis paper deals with the control problem of an engine air path system with the air mass flow and EGR rate as the outputs and throttle valve and EGR valve as inputs. In the considered system, since the EGR response is slow compared with the response of the intake air mass, the overshoot and undershoot phenomena occur in fresh air mass flow during transient response. Moreover, the mechanical restriction of the valves opening range results in instability of the control system. In this paper, we propose an anti-windup predictive control taking into inputs restriction for air path system to improve transient performance and to maintain the stable air path system.
