A study on the electronic EGR valve control method S a n g -Yu nCh o i 1 ,S a n g -Hu nL e e 2 a n dS e o n -b o n gL e e Abstract As environmental awareness increases, regulations on exhaust gas of automobile, which is a cause of air pollution, have been strengthened. In order to meet emission regulation, automobile companies and engine manufacturers have actively developed the related technologies. Because the emission control has become severe, the systems using electronic motor or solenoid valve for high precise control are needed. For this reason, it is required not only the optimization of composition of components for improving performance and efficiency of the system but also the development of optimal design technology of electronic control system by securing the designing and manufacturing technology of the components. In this paper, it is proposed the position characteristics for electronic EGR valve module through the applied control logic and experiment results.

Design and Implementation of a Linear Active Disturbance Rejection Control-Based Position Servo Control System of an Electromotive Valve for Exhaust Gas Recirculation

“…In response to the above problems, PID and its improvement methods are widely used for EGR valve position control. Choi et al [ 16 ] used a three-loop cascade control method to achieve the position control of the EGR valve. H.J.…”
