Feedback Stability Under Mixed Gain and Phase Uncertainty
Jiajin Liang, Di Zhao, Li Qiu
In this study, we investigate the robust feedback stability problem for multiple-input-multiple-output linear time-invariant systems involving sectored-disk uncertainty, namely, dy…

A Cyclic Small Phase Theorem
Chao Chen, Wei Chen, Di Zhao +2
This paper introduces a brand-new phase definition called the segmental phase for multi-input multi-output linear time-invariant systems. The underpinning of the definition lies in…
