摘要： 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.

摘要： 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.

摘要： 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.
