Abstract :
A PID control is developed for robust control of EGR (Exhaust Gas Recirculation) system in a gasoline engine. First a GT-power model of the gasoline engine with EGR system was built and verified. Then a PID controller was built using Simulink/Matlab and coupled with the GT-power engine model. A suitable tuning strategy for the PID controllers is also developed. Its response characteristics and performance are investigated in details. The results show that this PID control system is robust, fast and have good anti-interference performance, which make it very suitable for the variable complicated work condition of gasoline engine.
