ACCOMPLISHMENTS
- Performance improved by reducing
vibration settling time
- Method can be applied to new
systems quickly
- Method robust - insensitive
to system or environmental changes
- Effectively eliminates sway
on large crane systems
|
COMMERCIALIZATION
- Seagate computer disk head testing
machine over three times faster with Input ShapingTM
- Input ShapingTM
software enables Seagate to more than double throughput of disk
head manufacturing
- Several linear motion and machine
tool manufacturers are implementing Input ShapingTM
- Input ShapingTM
has been implemented on a standard Programmable Logic Controller
(PLC) and is now being sold as an anti-sway device for cranes as
the No-SwayTM
system

GOVERNMENT/SCIENCE
APPLICATIONS
- Increased the performance of
space shuttle Endeavor payload experiment (Mid-Deck Active Control
Experiment, May 2, 1995)
- Available for use on upcoming
space-bound payloads
- Input ShapingTM
has been installed on large capacity cranes at the DOE Savannah
River facility and at Argonne National Labs
