Abstract

Load stability systems and methods for stabilizing swinging motions of suspended loads. The load stability systems include a fully automated, self-powered device that employs thrust to counteract and control lateral and rotational motion of an external load. The device is a temporary installment on the load, cable, or boom, and is agnostic to the platform from which it is suspended.

Claims (38)

1. A load stability system apparatus for controlling a motion of a load suspended via a cable from above, the apparatus comprising:

a cable attachment structure, wherein the cable attachment structure is to secure the load stability system apparatus to the cable;

a load attachment structure, wherein the load attachment structure is to secure the load below load stability system apparatus;

a sensor array;

a thruster controller;

two or more thrusters, wherein the two or more thrusters are controlled by the thruster controller;

a processor and memory operably connected to the sensor array and the thruster controller, wherein the memory comprises instructions which, when executed by the processor, cause the load stability system apparatus to determine an estimate of a state of the load stability system based on a sensor data from the sensor suite, determine a thrust application vector to move the load stability system apparatus and load toward at least one of a desired orientation, desired location, or desired relative position of the load stability system apparatus and load, use the thrust controller to output a rotational thrust from one of the two or more thrusters to orient the load stability system apparatus along the thrust application vector, and output a thrust along the thrust application vector to move the load stability system apparatus and load toward at least one of the desired location or the desired relative position; and

wherein the state comprises a position, orientation, and motion of the load stability system apparatus and wherein to determine the state of the load stability system based on the sensor data comprises to fuse and filter the sensor data in a non-linear filter.

2. The load stability system apparatus according to claim 1 , wherein the non-linear filter comprises a non-linear flavor of a Kalman filter.

3. The load stability system apparatus according to claim 1 , wherein the desired orientation, desired location, or desired relative position of the load stability system apparatus and load is obtained from a command state.

4. The load stability system apparatus according to claim 3 , wherein the command state comprises at least one of idling, moving to a location, holding position, maintaining orientation, position, or location relative to a carrier, or directing control based on user input.

5. The load stability system apparatus according to claim 1 , wherein the load stability system apparatus comprises a tensile structure, wherein the tensile structure transfers force from the load to the cable and wherein the tensile structure comprises a rotational bearing to allow the load stability system apparatus to rotate separately from the cable.

6. The load stability system apparatus according to claim 1 , wherein the load stability system apparatus comprises at least one of batteries or a wireline power connection to a carrier.

7. The load stability system apparatus according to claim 1 , wherein the two or more thrusters have a fixed orientation within the load stability system apparatus.

8. A computer implemented method for controlling a load suspended via a cable from above, comprising:

determining an estimate of a state of the load based on a sensor data from a sensor suite;

determining a thrust application vector to move the load toward at least one of a desired orientation, desired location, or desired relative position of the load;

outputting a rotational thrust from one of the two or more thrusters to orient the load along the thrust application vector; and

outputting a thrust along the thrust application vector to move the load toward at least one of the desired location or the desired relative position; and

wherein the state comprises a position, orientation, and motion of the load stability system apparatus and wherein determining the state of the load based on the sensor data comprises fusing and filtering the sensor data in a non-linear filter.

9. The method according to claim 7 , wherein the non-linear filter comprise a non-linear flavor of a Kalman filter.

10. The method according to claim 7 , further comprising obtaining the desired orientation, desired location, or desired relative position of the load from a command state.

11. The method according to claim 9 , wherein the command state comprises at least one of idling, moving to a location, holding position, maintaining orientation, position, or location relative to a carrier, or directing control based on user input.

12. The method according to claim 7 , further comprising transferring force from the load to the cable via a tensile structure and isolating the cable from rotation of the load with a rotational bearing.

13. The method according to claim 7 , further comprising obtaining power from at least one of a battery or a power connection with a carrier.

14. An apparatus for control of a motion of a load suspended via a cable from above, the apparatus comprising:

means for a cable attachment structure, wherein the cable attachment structure is to secure the apparatus to the cable;

means for a load attachment structure, wherein the load attachment structure is to secure the load below the apparatus;

means for a sensor array, wherein the sensor array comprises means to obtain a sensor data;

means for a thruster controller;

means for two or more thrusters and means for the two or more thrusters to be controlled by the thruster controller;

means for a processor and memory to determine an estimate of a state of the load based on the sensor data from the sensor suite, determine a thrust application vector to move the load apparatus and load toward at least one of a desired orientation, desired location, or desired relative position of the apparatus and load, use the thrust controller to output a rotational thrust from one of the two or more thrusters to orient the load stability system apparatus along the thrust application vector, and output a thrust along the thrust application vector to move the apparatus and load toward at least one of the desired location or the desired relative position; and

wherein the state comprises a position, orientation, and motion of the load stability system apparatus and wherein means to determine the state of the load stability system based on the sensor data comprises means to fuse and filter the sensor data in a non-linear filter.

15. The apparatus according to claim 13 , wherein the non-linear filter comprises a non-linear flavor of a Kalman filter.

16. The apparatus according to claim 13 , further comprising means to obtain the desired orientation, desired location, or desired relative position of the apparatus and load from a command state.

17. The apparatus according to claim 15 , wherein the command state comprises at least one of idling, moving to a location, holding position, maintaining orientation, position, or location relative to a carrier, or directing control based on user input.

18. The apparatus according to claim 13 , further comprising means to provide power to the apparatus via at least one of batteries or power from a carrier.

19. The apparatus according to claim 13 , wherein the means for two or more thrusters comprise means for two or more thrusters with fixed orientation within the apparatus.
