== Control of high-altitude electricity-generating wind-power kite systems ==
{{See also|High altitude wind power}}
Human control of high altitude wind power systems is typically accomplished through [[servomechanism|servo mechanisms]], as the tether tensions are too great for direct manual operation.<ref>{{Cite web |url=http://www.sequoia.it/documentirotokite/rotokiteeng.pdf |title=High altitude wind power generation with the use of kites |access-date=2009-12-07 |archive-url=https://web.archive.org/web/20110722052921/http://www.sequoia.it/documentirotokite/rotokiteeng.pdf |archive-date=2011-07-22 |url-status=dead }}</ref><ref>[http://www.kitegen.com/pdf/ACCNewYork2007.pdf KiteGen project: control as key technology for a quantum leap in wind energy generators] by M.

There are a number of patents in this area:
* Kite control systems by John D. Bellacera
* Several patents by Dominique and Bruno Legaignoux<ref>[http://www.inflatablekite.com/siteinf/fr/InfBrevets.html Patents by Dominique and Bruno Legaignoux] In 1984 a fundamental first patent gave them impetus to later bring forward several other key kite control patents.</ref>

Other concepts include:
* Pulling the lines using winches
* Rotating the line attachment points around a central pivot.<ref>[https://www.youtube.com/watch?v=_8umgx4h2Us Kite test 2] of the Sussex University kite control project.</ref>
* Shifting the line attachment points back and forth (or up and down) using linear motors
