Fuzzy Networked Control Systems Design Considering Scheduling Restrictions

open access: yesAdvances in Fuzzy Systems, Volume 2012, Issue 1, 2012., 2012
Nowadays network control systems present a common approximation when connectivity is the issue to be solved based on time delays coupling from external factors. However, this approach tends to be complex in terms of time delays. Therefore, it is necessary to study the behavior of the delays as well as the integration into differential equations of ...
