CLOSED-LOOP FEEDBACK CONTROL USING MOTION CAPTURE SYSTEMS

摘要

PROBLEM TO BE SOLVED: To provide novel systems and methods that mitigate undesirable aspects of prior-art control systems such as increasing weight and cost of a vehicle and not providing required accuracy and update frequency in control systems that use on-board sensors, for example.SOLUTION: A system includes a motion capture system 420 configured to measure motion characteristics of one or more controllable devices 410 when the controllable devices are operating within a control volume. A processor 402 receives the measured motion characteristics from the motion capture system and determines a control signal. A position control system receives the control signal and continuously adjusts the motion characteristics of the one or more controllable devices in order to maintain or achieve a desired motion state. The controllable device may be equipped with passive retro-reflective markers 426. The motion capture system, the processor, and the position control system comprise a complete closed-loop feedback control system.
