On the Necessity and Sufficiency of Discrete-Time O'Shea-Zames-Falb Multipliers
Lanlan Su, Peter Seiler, Joaquin Carrasco +1
This paper considers the robust stability of a discrete-time Lurye system consisting of the feedback interconnection between a linear system and a bounded and monotone nonlinearity…
A Frequency-Domain Approach to Nonlinear Negative Imaginary Systems Analysis
Di Zhao, Chao Chen, Sei Zhen Khong
In this study, we extend the theory of negative imaginary (NI) systems to a nonlinear framework using a frequency-domain approach. The extended notion is completely characterized v…
The Singular Angle of Nonlinear Systems
Chao Chen, Di Zhao, Sei Zhen Khong
In this paper, we introduce an angle notion called the singular angle for nonlinear systems from an input-output perspective. The proposed system singular angle, based on the angle…
A Phase Theory of MIMO LTI Systems
Wei Chen, Dan Wang, Sei Zhen Khong +1
In this paper, we define the phase response for a class of multi-input multi-output (MIMO) linear time-invariant (LTI) systems whose frequency responses are (semi-)sectorial at all…
