Switched system approach to distributed guaranteed cost control for interconnected systems with communication unreliability

摘要

This study presents a switched system approach to distributed guaranteed cost control for a class of interconnected systems, where the subsystems of the interconnected system are coupled via states. In the proposed scheme, the subsystems communicate with each other through a network with communication losses caused by the communication constraint or network attacks. The communication-based interconnected system is modelled as a switched system with parameters uncertainties in system matrixes induced by sampling jitter and network time-varying delays. The stability analysis and guaranteed cost controller design are presented by applying the average dwell time method. Meanwhile, a quantitative relation between the system performance and the communication quality is established. Finally, numerical simulations are given to show the effectiveness of the proposed results.
