Abstract: A fuel injector controller is disclosed. The fuel injector controller may determine respective values of a set of parameters of the engine; process, using a neural network, the respective values to determine a target fuel output of a fuel injector, wherein the neural network is configured to determine the target fuel output based on the set of parameters being an input layer of the neural network; determine, based on an output of the neural network, the target fuel output; and provide the determined target fuel output to the fuel injector to permit the fuel injector to inject fuel according to the target fuel output.

Abstract: A method for controlling an internal combustion engine system including a particulate filter includes receiving a desired output for an internal combustion engine and receiving sensor information including information indicative of a quantity of soot in the particulate filter. The method includes calculating a plurality of sets of engine performance values based on respective sets of candidate control points, each set of engine performance values including a soot change rate at which the quantity of soot changes over time and determining whether the soot change rate satisfies a soot change rate limit that requires an increase in the quantity of soot in the particulate filter. The method also includes controlling the internal combustion engine based on a set of candidate control points that satisfies the soot change rate limit.

Abstract: Power system optimization calibration is disclosed. An example implementation includes receiving, by an engine control module, calibration information associated with optimizing an operating characteristic of a power system; determining, by the engine control module and using an optimization model, an optimization profile to optimize the operating characteristic, wherein the optimization model is configured to perform one or more optimization processes to determine, according to the calibration information, optimized values associated with adjustable parameters of the power system, wherein the optimization profile is configured to include the optimized values; and configuring, by the engine control module, a first control device, associated with a first adjustable parameter of the adjustable parameters, according to the optimization profile, wherein the first control device is configured to control a first component of an engine of the power system to be set according to an optimized value for the first adjustable parameter.

Abstract: A damage analysis and control system is disclosed. An example process may include receiving a data set of measurements associated with a period of operation of a power system. The data set of measurements may identify a frequency that the power system is in an operating state during the period of operation, and the data set of measurements may identify a frequency of damage measurements associated with the operating state. The process may include determining, using a damage model and the data set of measurements, a damage score for the operating state during the period of operation of the power system. The process may include determining that the damage score satisfies a threshold damage score associated with the damage model and performing an action associated with the power system based on the damage score satisfying the threshold damage score.

Abstract: Power system optimization is disclosed. An example power system described herein may include an engine control module that receives measurements associated with sensors, identifies settings associated with control devices, determines that a first set of parameters associated with the one or more control devices is to be optimized according to a first optimization process, iteratively performs the first optimization process until the first set of parameters are optimized, determines that a second set of parameters associated with the one or more control devices are to be optimized according to a second optimization process, iteratively performs the second optimization process until the second set of parameters are optimized, and, after the second set of parameters are optimized according to the second optimization process, configures one of the control devices to operate using an optimized value for the control device determined using the second optimization process.
