摘要： A machine includes an engine, a selective catalytic reduction (SCR) element fixedly connected to an output of the engine, and a controller. The controller is communicatively coupled to the engine and a sensor at an output of the SCR element. The controller is configured to calculate an estimated amount of emissions at a location of the SCR element, calculate an estimated amount of emissions from an output of the SCR element, measure, using the sensor, an actual amount of emissions from the output of the SCR element, and perform a comparison of the estimated amount of emissions and the actual amount of emissions. The controller is further configured to adjust, based on the comparison, the estimated amount of emissions at the location of the SCR element, and control operation of the engine based on the adjusted amount of emissions.

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.
