Prediction-based trajectory tracking of external gas recirculation for turbocharged SI engines

Abstract : This paper addresses the trajectory tracking problem of intake burned gas rate for Spark Ignited engines. We propose a simple linear time-varying input delay model of this dynamics, where the delay is represented by an implicit integral equation involving the past values of the input. We extend some recent results from the literature to design a novel predictor-based controller and compare the merits of the proposed technique with the ones of previous works from the literature. Simulation results stress the relevance of this preliminary work and directions of future work are provided.
