some of the more than two dozen articles Chez Hardy has produced for
the Motion Control Association's
website:
Observer
Control Improves Motion
By combining mathematical models with encoder data, observer control
decreases settling time and decreases error by a factor of 30. (February
2008)
Smart
Drives Take Control
A new generation of drives with embedded digital signal processors
reduces cost, simplifies maintenance, and even performs control operations.
(January 2008)
Motors
Get Smart
Integrated motors combine drivers and controllers and sometimes even
encoders with the motor itself to provide self-contained, swappable
units.
(November 2007)
Ethernet
Pulls Motion Together
Ethernet shows great promise for motion control, provided the underlying
transport layer is maintained. (October 2007)
Cleanrooms:
Sweating the Small Stuff
Using cleanroom grease, vacuum, careful cable design, and appropriate
coatings, system designers can achieve motion control in cleanroom
conditions. (October 2007)
The
Bliss of BiSS
Open-source protocol for absolute encoders offers networking benefits
(October 2007)

recent progress and obstacles that remain. (July 1997)
Semiconductor
manufacturers look to short wavelengths
A feverish development is underway to bring 193-nm lithography online
by 1999, but the challenges are daunting.
Materials
challenge 193-nm optics
193-nm stepper developers face issues of high absorption, optical
compaction, and new materials.
Mask
