Abstract

This paper considers multi-weighted and multi-delayed large-scale interconnected systems, which have multiple coupling links between neighboring subsystems and all links have different coupling weights and delays. It describes an event-triggered distributed dynamic output-feedback control approach for dissipative stabilization of the concerned systems under quantization, packet dropouts and stochastic deception attacks. An event-triggered distributed dynamic output feedback controller (DOFC) is constructed and sufficient conditions are calculated for the exponential mean square stability along with a strict ( Q, S, R)-dissipative performance of the considered large-scale systems. The control gains for the subsystem controllers are determined by solving a nonlinear minimization problem using the cone complementarity linearization (CCL) algorithm. Finally, the obtained results are verified through a numerical example consisting of a continuous stirred tank reactor (CSTR) system.
