Modeling for HCCI Control

Research output: Chapter in Book/Report/Conference proceedingPaper in conference proceeding

Abstract

Due to the possibility of increased efficiency and reduced emissions, Homogeneous Charge Compression Ignition (HCCI) is a promising alternative to conventional internal combustion engines. Ignition timing in HCCI is highly sensitive to operating conditions and lacks direct actuation, making it a challenging subject for closed-loop control. This paper presents physics-based, control-oriented modeling of HCCI including cylinder wall temperature dynamics. The model was calibrated using experimental data from an optical engine allowing measurements of the cylinder wall temperature to be made. To further validate the model, it was calibrated against a conventional engine and linearizations of the model were used to design model predictive controllers for control of the ignition timing using the inlet valve closing and the intake temperature as control signals. The resulting control performance was experimentally evaluated in terms of response time and steady-state output variance.
