Soft and Hard Scaled Relative Graphs for Nonlinear Feedback Stability
Chao Chen, Sei Zhen Khong, Rodolphe Sepulchre
This article presents input-output stability analysis of nonlinear feedback systems based on the notion of soft and hard scaled relative graphs (SRGs). The soft and hard SRGs ackno…

On phase in scaled graphs
Sebastiaan van den Eijnden, Chao Chen, Koen Scheres +2
The scaled graph has been introduced recently as a nonlinear extension of the classical Nyquist plot for linear time-invariant systems. In this paper, we introduce a modified defin…

Graphical Dominance Analysis for Linear Systems: A Frequency-Domain Approach
Chao Chen, Thomas Chaffey, Rodolphe Sepulchre
We propose a frequency-domain approach to dominance analysis for multi-input multi-output (MIMO) linear time-invariant systems. The dominance of a MIMO system is defined to be the…
