| Abstract: | The electronical control management system for a small displacement gasoline engine is developed.Based on the research of various characteristics in different idle phases,key factor of control and emission requirement of idle state are analysed.Combined with expert control system,variational parameters PID control,forecast control,and Idle self-adapt control,advanced control strategys are studied.The system used different advanced control arithmetics to do experiment of idle state and calibrate various control paramenters.The idle state control parameters were optimized according to different loads of engine.At the same time,the system used ignition advance angle to realize torque fluctuating balance control.So the system can realize idle speed control stabilization of engine. |
