Abstract

An apparatus comprised of a power source, a set of primary loads, a set of life extension loads, and a controller. The power source is capable of supplying power and the set of primary loads is capable of being operated using the power. The set of life extension loads is capable of being operated using the power and capable of extending life of the set of primary loads. The controller is capable of controlling an operation of the set of primary loads and the set of life extension loads to optimize a total systems operating metric consisting of performance, energy use, and life to reduce a total cost.

Claims

1. An apparatus comprising:

a power source capable of supplying power;

a set of primary loads capable of being operated using the power;

a set of life extension loads capable of being operated using the power and capable of extending a life of the set of primary loads; and

a controller capable of controlling an operation of the set of primary loads and the set of life extension loads based on performance, energy use, and life to reduce a total cost.

2. The apparatus of claim 1 further comprising:

a model of the set of primary loads and the set of life extension loads, wherein the model provides information about the performance, the energy use, and the life for the set of primary loads and the set of life extension loads.

3. The apparatus of claim 1, wherein the controller controls the performance and the energy use by the set of primary loads and the set of life extension loads to meet a policy for at least one of the performance, the energy use, and the life.

4. The apparatus of claim 1, wherein in controlling the operation of the set of primary loads and the set of life extension loads, the controller is capable of controlling the power supplied to the set of primary loads and the set of life extension loads.

5. The apparatus of claim 4, wherein the controller is capable of controlling the power used by the set of primary loads and the set of life extension loads.

6. The apparatus of claim 1, wherein the controller increases the energy use for a life extension load in the set of life extension loads to increase a related life of an associated primary load and wherein an associated total cost for the life extension load and the associated primary load is reduced.

7. The apparatus of claim 1, wherein the controller increases a first associated life of a selected primary load in the set of primary loads by decreasing a second associated life of a selected life extension load in the set of life extension loads and wherein the associate total cost for the selected primary load and the selected life extension load is reduced.

8. The apparatus of claim 1, wherein a life extension load within the set of life extension loads is used to extended the life of the power source.

9. The apparatus of claim 8, wherein the controller controls the life extension load to reduce a cost of the life extension load and the power source.

10. The apparatus of claim 1, wherein the set of primary loads comprises at least one of a hydraulic system, avionics, a landing gear system, an engine, a brake system, an environmental control system, a navigation system, and an in-flight entertainment system.

11. The apparatus of claim 1, wherein the set of life extension loads comprises at least one of a liquid cooling system, a ram air cooling system, an extended cooling system, a vibration control device, an acoustic control device, a power filtering unit, a fluid filtering unit, and a lubrication unit.

12. The apparatus of claim 1 further comprising:

a vehicle, wherein the power source, the set of primary loads, the set of life extension loads, and the controller are located within the vehicle.

13. The apparatus of claim 12, wherein the vehicle is selected from one of aircraft, a spacecraft, a land vehicle, and an aquatic vehicle.

14. The apparatus of claim 1 further comprising:

a land based structure, wherein the power source, the set of primary loads, the set of life extension loads, and the controller are located within the land based structure.

15. An apparatus comprising:

a load; and

a controller capable of controlling an operation of the load based on performance, energy use, and life time to reduce a total cost of the load.

16. The apparatus of claim 15 further comprising:

a life extension load capable of extending a life of the load, wherein the controller is capable of controlling the operation of the life extension load based on the performance, the energy use, and the life time to reduce the total cost of the load and the life extension load.

17. The apparatus of claim 16 further comprising:

a power source capable of supplying power to the load and the life extension load.

18. The apparatus of claim 17, wherein in controlling the operation of the load, the controller is capable of controlling the power supplied to the load.

19. A method for operating a set of loads, the method comprises:

monitoring a set of parameters and energy use for the set of loads;

identifying a remaining life for the set of loads; and

changing at least one of performance and energy use for the set of loads to reduce a total cost for the set of loads based on a policy.

20. The method of claim 19, wherein the changing step comprises:

increasing the energy use by a life extension load in the set of loads to increase a life of a primary load in the set of loads, wherein the total cost of the set of loads is reduced; and

decreasing a performance of the primary load in the set of loads to cause at least one of an increase in the life of the primary load and a reduction in the energy use of the primary load, wherein the total cost of the set of loads is reduced.
