摘要：
A system includes an engine comprising an EGR valve that recirculates a portion of exhaust gas, a data repository that stores a first look up and one or more engine operational parameters, an engine control unit operationally coupled to the engine and the data repository, wherein the engine control unit is configured to: determine a desired EGR flow rate reference of the portion of the exhaust gas based on the one or more engine operational parameters and the first look up table, determine a current estimated EGR flow rate based on the one or more engine operational parameters, determine a designated corrected EGR flow rate reference based on the desired EGR flow rate reference and a delta EGR flow rate, determine EGR flow rate error, and determine a percentage opening of the EGR valve based at least on the EGR flow rate error.
