Frontiers of Information Technology & Electronic Engineering 2022, Volume 23, Issue 3,   Pages 382-397 doi: 10.1631/FITEE.2000596

Abstract: Analyzing under various circumstances is generally regarded as a challenging problem. Robustness against failure is one of the essential properties of large-scale dynamic network systems such as s, transportation systems, communication systems, and computer networks. Due to the network diversity and complexity, many topological features have been proposed to capture specific system properties. For s, a popular process for improving a network’s structural robustness is via the topology design. However, most of existing methods focus on localized network metrics, such as node connectivity and edge connectivity, which do not encompass a global perspective of cascading propagation in a . In this paper, we use an informative global metric because it is sensitive to the connectedness in a broader spectrum of graphs. Our process involves decreasing the in a by minimizing the increase in its . We propose a topology-based greedy strategy to optimize the robustness of the . To evaluate the , we calculate the using MATCASC to simulate cascading line outages in s. Experimental results illustrate that our proposed method outperforms existing techniques.

Stabilization of switched linear systems under asynchronous switching subject to admissible edge-dependent average Research Article

Linlin HOU, Xuan MA, Haibin SUN,houtingting8706@126.com,maxuan24@163.com,fengyun198212@163.com

Frontiers of Information Technology & Electronic Engineering 2022, Volume 23, Issue 5,   Pages 810-822 doi: 10.1631/FITEE.2000698

Abstract: The problem of stabilizing switched linear systems under is addressed. The method is applied to design a switching signal that comprises slow and fast . Under this switching signal, the restriction that the maximum delay of is known in advance is removed. The constructed Lyapunov function is associated with both the system mode and controller mode. The stabilization criteria and the corresponding algorithm are presented to obtain the controller gains and to design the switching signal. Finally, two examples are given to demonstrate the effectiveness of the proposed results.
