Abstract: A control system to optimize response time of a plurality of engines of a machine is provided. The control system includes a controller configured to determine a first engine group and a second engine group based on data regarding response time characteristics of the plurality of engines, control the first engine group to increase output power of the machine when the output power of the machine is below a predetermined power output threshold, and control the second engine group to increase output power of the machine responsive to the output power of the machine reaching the predetermined power output threshold. A response time of the first engine group is faster than a response time of the second engine group when the output power of the machine is below the predetermined power output threshold.

Abstract: A power system for powering a load is provided. The power system includes a plurality of power sources with each power source including an engine. A SCR system is associated with the engine of at least one of the plurality of power sources. A controller is in communication with the plurality of power sources. The controller is configured to receive engine operation information, emission output information associated with each engine and conversion efficiency information associated with the SCR system and selectively apportion the power demand presented by the load between each of the plurality of power sources based on minimizing total engine emissions across the plurality of power sources and using the engine operation information, the emission output information and the conversion efficiency information.

Abstract: A control system implementing a hybrid energy storage system (ESS) optimization strategy is disclosed. The hybrid ESS optimization strategy may be implemented in a machine that comprises a power system that includes a plurality of power sources and a power controller that includes one or more processors. The power controller may receive information related to a set of brake-specific fuel consumption (BSFC) maps associated with the plurality of power sources, determine a performance indicator using a cost function associated with the plurality of power sources, and generate a command to operate the power system based on a power distribution that minimizes an energy cost to operate the power system based on the information related to the set of BSFC maps, the performance indicator, and a load associated with the power system.

Abstract: A system may determine configuration information associated with a power system for a work site that includes one or more power sources. The system may determine respective operation parameters of the one or more power sources and one or more performance criteria associated with the power system. The system may determine a baseline operation plan for the power system. The system may identify an optimization analysis technique and may process, using the optimization analysis technique, the configuration information associated with the power system, the respective operation parameters of the one or more power sources, and the one or more performance criteria associated with the power system to generate the optimized operation plan for the power system. The system may cause, based on the baseline operation plan for the power system and the optimized operation plan for the power system, one or more actions to be performed.

Abstract: A method of operating a plurality of power sources is provided. The method includes operating a first power source at a first power output and operating a second power source at a second power output. The second power source has a second operational capacity greater than the first operational capacity. First transient zone parameters are determined to operate in a first transient output power range. The first transient zone parameters include a first planned power output and a second planned power output constrained to be less than the first operational capacity.

Abstract: A regeneration control system for an exhaust filter in an internal combustion engine system includes a first sensing mechanism for monitoring an exhaust flow resistance of the exhaust filter, and a second sensing mechanism for monitoring an attenuation of electromagnetic energy transmitted through the exhaust filter. The regeneration control system further includes an electronic controller coupled with the sensing mechanisms and configured to output a filter regeneration command responsive to an amount of particulate matter trapped within the exhaust filter. The electronic controller is further configured to weight data from the first and second sensing mechanisms in determining the amount of particulate matter. Weighting of the data may be responsive to an operating state of the internal combustion engine system. Related methodology is also disclosed.
