A Fuzzy Intelligent-Integration PID Idle Control Strategy for Gas Fueled SI Engine

摘要

A fuzzy intelligent-integration PID control strategy is developed on an LPG single-gas-fuel sequence injection SI engine and is employed to control its idle speed. The algorithm is processed by an ECU with an Infineon XC2787 MCU. Experiment is conducted on a passenger car's LPG single-gas-fuel engine. The experiment results demonstrate that the control strategy developed in this paper has relatively little static errors and improves step response.
