A hybrid feedback for a benchmark problem of idle speed control

The ever increasing demands on passengers' comfort safety, emissions and fuel consumption imposed by car manufacturers and regulations call for advanced techniques and the use of cycle-accurate models in automotive control. In this paper, we focus on such approach to the idle speed control. It is natural to resort to hybrid methodologies, because of the rich combination of time and event-based behaviors exhibited by a controlled engine. A hybrid benchmark problem is considered and addressed first by analyzing the equilibria of the system and then testing a simple hybrid feedback strategy. Copyright (C) 2009 John Wiley & Sons, Ltd.
