Abstract: A control system for a machine may include an electronic controller configured to receive a sensor signal indicative of an operational parameter of the machine, and to output a control signal to an actuator to control an operational characteristic of the machine. The electronic controller may include a poles-zeros identification module, an onboard system identification module configured for online, real-time identification of one or more transfer functions that govern a dynamic relationship between one or more inputs and one or more outputs of at least one plant model, wherein the at least one plant model is representative of behaviors of the machine and simulates a dynamic influence of the operational parameter, and a comparator that determines the accuracy of a plant model.

Abstract: A method and a system of managing load sharing among a plurality of power sources are disclosed. According to certain embodiments, the method includes determining a total power output to be directed from the plurality of power sources to at least one power consumer. The method also includes retrieving a Brake Specific Fuel Consumption (BSFC) curve associated with each of the plurality of power sources. The method further includes determining an operating priority for each of the plurality of power sources based on operating constraints associated with the respective power source. The method further includes determining a load share for each of the plurality of power sources based on at least the total power output, the BSFC curves, and the operating priorities.
