Abstract:
1. A method for controlling a system having a plurality of components, the method comprising: determining, via a controller, a normalized state of health (SOH) value for each of the components, wherein a normalized SOH value of 1 corresponds to a calibrated or new component and a normalized SOH value of 0 corresponds to a non-functioning component; determining a state of function (SOF) value of the system as a function of the SOH value of each of the components; estimating a remaining useful life of the system using the SOF value of the system; estimating a plurality of different component-level costs via a component-level costing model, wherein each component-level cost is an estimated cost of extending the life of a respective one of the components; determining, via a system-level costing model, a cost of each of a plurality of different control strategies as a function of the estimated component-level costs; selecting a control strategy from the plurality of different control strategies which minimizes operating costs while producing a threshold SOF value and a threshold remaining useful life of the components; and dynamically executing the selected control strategy via the controller.
