Market based control of structural movement
First Claim
1. A distributed market based control assembly for applying a force to a structure comprising:
- multiple actuators, each of the multiple actuators having an actuator controller that is responsive to an electrical signal representative of price information to control an applied force produced by the actuator on the structure; and
an electrical conductor for transmitting voltage and accumulating charge, referred to as a marketwire;
the price information being represented on the marketwire by analog fluctuations in an electrical characteristic of the marketwire;
the price information being dependent on the applied force produced by each actuator on the structure;
the marketwire being connected to each actuator controller to convey the price information to the actuator controllers without requiring any one of the actuators to communicate directly with any other one of the actuators.

Abstract
A distributed market based control assembly used in conjunction with fixed or movable structures. Typically multiple actuators are attached to the structure, with each of the multiple actuators having an actuator controller to control actuator applied force. Sensors are used for measuring structure movement, and a marketwire is connected to each actuator controller to convey price information to the actuator controllers by analog fluctuations in electrical characteristics of the marketwire. Actuators can be used to stabilize a fixed structure against movement, or alternatively can be used to control movement of movable structures from defined first positions to second positions (e.g. moving a robotic arm so its tip moves from point A to point B).
