The -Symmetric SRG with Applications to Stability of Cactus Dynamic Networks
Xiaokan Yang, Wei Chen, Li Qiu
In this paper, we systematically study a variant of the scaled relative graph (SRG), referred to as the -symmetric SRG, and apply it to the stability analysis of cactus networks…
Diversity and Interaction Quality of a Heterogeneous Multi-Agent System Applied to a Synchronization Problem
Xin Mao, Dan Wang, Wei Chen +1
In this paper, scalable controller design to achieve output synchronization for a heterogeneous discrete-time nonlinear multi-agent system is considered. The agents are assumed to…
The Small Phase Condition is Necessary for Symmetric Systems
Xiaokan Yang, Wei Chen, Li Qiu
In this paper, we show that the small phase condition is both sufficient and necessary to ensure the feedback stability when the interconnected systems are symmetric. Such symmetri…
Synchronization of Diverse Agents via Phase Analysis
Dan Wang, Wei Chen, Li Qiu
In this paper, the synchronization of heterogeneous agents interacting over a dynamical network is studied. The edge dynamics can model the inter-agent communications which are oft…
Optimal -Matrix Completion with Majorization Ordered Objectives (To the memory of Pravin Varaiya)
Yanfang Mo, Wei Chen, Keyou You +1
We propose and examine two optimal -matrix completion problems with majorization ordered objectives. They elevate the seminal study by Gale and Ryser from feasibility to opt…
On the Phases of a Semi-Sectorial Matrix
Li Qiu, Dan Wang, Xin Mao +1
In this paper, we extend the definition of phases of sectorial matrices to those of semi-sectorial matrices, which are possibly singular. Properties of the phases are also extended…
Gain and phase type multipliers for feedback robustness
Axel Ringh, Xin Mao, Wei Chen +2
It is known that the stability of a feedback interconnection of two linear time-invariant systems implies that the graphs of the open-loop systems are quadratically separated. This…
When Small Gain Meets Small Phase
Di Zhao, Wei Chen, Li Qiu
In this paper, we investigate the feedback stability of multiple-input multiple-output linear time-invariant systems with combined gain and phase information. To begin with, we exp…
