Nowadays, Network Control Systems represent a common solution when solving connectivity issues for distributed control systems. However, this approach tends to increase time complexity in terms of time delays, and thus, making necessary the study of behavior of such time delays as well as local structure and the differential equations which model such a behavior. Time delays need to be known a priori, but from a dynamic, real-time behavior. To do so, this paper presents the use of a dynamic, priority exchange scheduling for bounding time delays. The objective is to show how to tackle multiple time delays, as well as faults that produce variable structure onto dynamic model and the dynamic response from real-time scheduling approximation. The novelty of this approach is to use both, the appearance of faults and time delays, as perturbations considering nonlinear behavior through a fuzzy TKS approach with local observer for multiple state estimation, in a codesign strategy. The related control law is designed considering fuzzy logic for nonlinear time delays coupling and inherent local fault appearance. © 2013 ICIC International.
