Event-based output tracking control for fuzzy networked control systems with network-induced delays

摘要

This paper investigates the problem of event-based output tracking control with network-induced time-varying delays for nonlinear networked control systems (NCSs) approximated by interval type-2 (IT2) fuzzy systems. The membership functions (MFs) with upper and lower bounds are utilized to capture the uncertainties in the nonlinear systems. A novel IT2 fuzzy controller is designed, where the premise variables and MFs are asynchronous and different from those of the fuzzy systems. It is shown that the proposed adaptive event-based control mechanism for IT2 fuzzy NCSs is effective to reduce the utilization of limited network resources. Finally, simulation examples are applied to show the advantages of the presented approach.
