ICE Idle Speed Control Using Fuzzy Idle

摘要

In the present work, some investigations on the fuzzy control of a spark ignition (SI) engine operating in idle speed range are reported. Idle speed control is a common problem for automotive manufacturers because of the significant nonlinearities and time delays exhibited by the system. These features make the problem quite complex and justify an in-depth investigation of it. After addressing the modeling and analysis of the engine, two control variables, one controlling the opening of the air by-pass valve and the other the timing of the spark that differ sensibly in both their quantitative and temporal effectiveness, are used for simulation of addressed SI engine model in MATLAB/SIMULINK.
