Abstract

An automatic control system for an aircraft has a first controller connected to the pilot'"'"'s operating controls. The first controller manipulates the operating controls so that goals, expressed in terms of selected aircraft parameters, are achieved. A second controller supplies a series of goals to the first controller so that the aircraft will perform desired maneuvers. A third controller acts as a mission planner, and supplies desired maneuvers to the second controller in accordance with overall mission plans.

Claims

1. A control system for a vehicle, comprising:

vehicle controls for manipulating controllable functions of the vehicle;

a first control system coupled to said vehicle controls, said first control system adapted to manipulate the controllable functions to achieve predetermined goals, said predetermined goals being selected vehicle operating parameters;

a second control system coupled to said first control system and adapted for controlling said first control system by providing a series of goals to achieve predetermined maneuvers, wherein a series of consecutive goals defines a maneuver and a series of consecutive maneuvers defines a mission plan to be executed by the vehicle; and

a third control system coupled to said second control system, wherein said third control system includes a mission planner, and wherein said third control system controls said second control system and is adapted for providing a series of consecutive maneuvers to said second control system in accordance with a mission plan.

2. The system of claim 1, wherein said third control system monitors selected vehicle parameters, and wherein ongoing maneuvers can be interrupted at any time to initiate new maneuvers.

3. The system of claim 1, wherein the controlled vehicle is an aircraft.

4. The system of claim 3, wherein said first control system manipulates a control stick, rudder, and throttle of the aircraft.

5. The system of claim 1, wherein the vehicle is unmanned.

6. The system of claim 1, wherein said second control system monitors selected vehicle parameters, and wherein ongoing goals can be interrupted at any time to initiate new goals.

7. The system of claim 1, wherein at least one of the goals provided to said second control system comprises a waiting step wherein no further goals are provided to said first control system until selected vehicle parameters corresponding to previous goals reach selected values.

8. The system of claim 1, wherein said first control system is adapted to monitor selected vehicle operating parameters.

9. A control system for an aircraft, comprising:

a first controller coupled to aircraft controls for manipulating the aircraft controls, wherein said first controller is adapted to manipulate the aircraft controls to achieve predetermined goals, said predetermined goals being selected parameters of the aircraft;

a second controller coupled to said first controller for controlling said first controller by supplying thereto a series of goals to be achieved, wherein selected consecutive groups of goals define standard aircraft maneuvers; and

a third controller coupled to said second controller for controlling said second controller by selecting maneuvers to be performed in accordance with an overall mission plan;

wherein said second controller can change the goal supplied to said first controller without regard to whether a current goal has been achieved, wherein said third controller can change a selected maneuver without regard to whether a current maneuver has been completed, and wherein said third controller can supply goals directly to said first controller.

10. The control system of claim 9, wherein the control system operates on an aircraft piloted by a person, and wherein said first controller is coupled to pilot manipulable controls through servo mechanisms, and wherein said first controller manipulates the aircraft controls by actuating the pilot manipulable controls with the servo mechanisms.

11. The system of claim 9, wherein said first control system is adapted to monitor selected vehicle operating parameters.

12. A vehicle control system, comprising:

vehicle controls for manipulating controllable functions of the vehicle;

a first controller coupled to said vehicle controls and adapted to manipulate the controllable functions to achieve predetermined goals, said predetermined goals being selected vehicle operating parameters.

a second controller coupled to said first controller and adapted for controlling said first controller by providing a series of goals to achieve predetermined maneuvers, wherein a series of consecutive goals defines a maneuver to be executed by the vehicle; and

a third controller coupled to said second controller for controlling said second controller by selecting maneuvers to be performed in accordance with known conditions, said known conditions being current vehicle operating parameters.

13. The vehicle control system of claim 12, wherein said third controller monitors selected vehicle parameters, and wherein ongoing maneuvers can be interrupted at any time to initiate new maneuvers.

14. The vehicle control system of claim 12, wherein the second controller can change the current goal supplied to said first controller regardless of whether any such current goals have been achieved.

15. The vehicle control system of claim 12, wherein said third controller can supply goals directly to said first controller.

16. The vehicle control system of claim 12, wherein the vehicle is unmanned.

17. The vehicle control system of claim 12, wherein the first controller is adapted to monitor selected vehicle operating parameters.

18. The vehicle control system of claim 12, wherein the vehicle is an aircraft.

19. The vehicle control system of claim 18, wherein the first controller is adapted to manipulate a control stick, rudder and throttle of the aircraft.

20. The vehicle control system of claim 12, wherein at least one of the goals provided to said second controller comprises a waiting step wherein no further goals are provided to said first controller until selected vehicle parameters corresponding to previous goals reach selected values.

21. The vehicle control system of claim 12, wherein said known conditions include a mission plan.

22. A control system for an aircraft, comprising:

aircraft controls for manipulating controllable functions of the aircraft;

a first control system coupled to said aircraft controls and adapted to manipulate said aircraft controls to achieve predetermined goals, said predetermined goals being selected parameters of the aircraft;

a second control system coupled to said first control system for controlling said first control system by supplying thereto a series of predetermined goals to be achieved, wherein selected consecutive groups of goals define standard aircraft maneuvers; and

a third control system coupled to said second control system for controlling said second control system by selecting maneuvers to be performed in accordance with known conditions, said known conditions being mission plans and current vehicle operating parameters.

23. The control system of claim 22, wherein the aircraft is unmanned.

24. The control system of claim 22, wherein said third control system monitors selected vehicle parameters, and wherein ongoing maneuvers can be interrupted at any time to initiate new maneuvers.

25. The control system of claim 22, wherein the second control system can change the current goal supplied to said first control system regardless of whether any such current goals have been achieved.

26. The control system of claim 22, wherein the first control system is adapted to manipulate pilot manipulable controls, said pilot manipulable controls including a control stick, rudder and throttle of the aircraft.

27. The control system of claim 26, wherein the control system operates on an aircraft piloted by a person, and wherein said first controller is coupled to said pilot manipulable controls through servo mechanisms and wherein said first controller manipulates the aircraft controls by actuating the pilot manipulable controls with the servo mechanisms.

28. The control system of claim 22, wherein said third control system can supply goals directly to said first control system.

29. The control system of claim 22, wherein at least one of the goals provided to said second control system comprises a waiting step wherein no further goals are provided to said first control system until selected vehicle parameters corresponding to previous goals reach selected values.
