Valve control method |
摘要 |
A valve control method for controlling a closed valve position of an exhaust gas recirculation valve for an internal combustion engine includes a feedback correction loop generating a feedback variable by comparing the output of a valve position sensor to a desired closed valve position. The feedback variable is used to control an actuator coupled to the valve which cooperates with a compliant seat. Thus, the desired closed position is maintained in a ready to open state, reducing valve opening delay caused by biasing forces.
