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)
