A vehicle control system may determine a required tractive effort and/or a required braking effort to propel a vehicle system at a determined speed. The vehicle control system may determine a throttle setting or a brake setting to provide the required tractive effort and/or the required braking effort and communicate a control signal from a remote controller device to an onboard controller device. The vehicle control system may operate a propulsion system at the throttle setting and/or a brake system at the brake setting to move the vehicle system at the determined speed.

Vehicle control system and method

A method for predicting an anomaly in a combustor () is presented. The method includes receiving signals representative of parameters in one or more combustion cans () of the combustor, generating a plurality of patterns based on a permutation entropy window and the signals, identifying a plurality of pattern categories in the plurality of patterns, determining a permutation entropy based on the plurality of patterns and the plurality of pattern categories, and predicting an anomaly in the combustor based on the permutation entropy. The method further includes comparing the plurality of pattern categories to determined permutations of pattern categories if the anomaly is present in the combustor, and predicting a category of the anomaly based on the comparison of the plurality of pattern categories to the determined permutations of pattern categories.

Systems and methods for predicting an anomaly in a combustor

Systems and methods are provided for controlling exhaust gas recirculation (EGR). In one example, an engine system includes a first EGR valve coupling an exhaust manifold to an engine exhaust system, a second EGR valve coupling the exhaust manifold to an engine intake system, and a control unit. The control unit selectively adjusts a position of the first EGR valve based on a target amount, and adjusts a position of the second EGR valve based on the target amount and a position of the first EGR valve. Responsive to a first degradation condition of the first EGR valve, the control unit adjusts the position of the second EGR valve based on the target amount and based on a pressure of the first exhaust manifold, and responsive to a second degradation condition of the first EGR valve, adjusts the position of the second EGR valve based on the target amount.

A fault detection method for a selective catalytic reduction (SCR) system comprising an SCR reactor, includes receiving a plurality of operating parameters () of the SCR reactor from a plurality of sensors. The method also includes estimating a state of an adaptive reactor model () representative of the SCR reactor based on the plurality of operating parameters. The method also includes generating a feature parameter () based on the plurality of operating parameters and the estimated state of the adaptive reactor model. The method includes determining a fault in the SCR system () based on the feature parameter.
