Abstract:
1. A method comprising: determining a first power level required from a powered system having at least one power generating unit in order to produce a minimum power to accomplish a specified mission, the first power level corresponding to a first proportion of a maximum power output of the powered system; determining an emission output for the mission based on the first power level required from the powered system; determining at least an additional, second power level for use in controlling the at least one power generating unit to accomplish the mission, the second power level corresponding to a second proportion of the maximum power, wherein the second power level is determined before use of the second power level so that alternate use of the second power level and at least one of the first power level or a third power level corresponding to a third proportion of the maximum power will result in an overall resulting power and a lower emission output for the mission, the overall resulting power being proximate the minimum power required; and automatically controlling operation of the powered system by using the second power level alternately with the at least one of the first power level or the third power level.
