    Abstract: 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.

    Abstract: A system includes a combustion engine having an intake manifold and an exhaust manifold, an exhaust gas recirculation (EGR) system coupled to the combustion engine and configured to route exhaust generated by the combustion engine from the exhaust manifold to the intake manifold, and a first knock sensor coupled to the combustion engine and configured to measure vibrations of the combustion engine and output a first vibration signal. The system also includes a controller communicatively coupled to the combustion engine, the knock sensor, the EGR system, or any combination thereof. The controller is configured to determine a peak firing pressure (PFP) within the combustion engine and control operations of both the combustion engine and the EGR system based on the PFP.
