Asymptotic stabilization for nonlinear systems with time‐varying delays

open access: yesIET Control Theory & Applications, 2023
In this paper, asymptotic stabilization problem for a class of nonlinear systems with unknown time‐varying delays is addressed. With the introduced static gain functions and new Lyapunov–Krasovskii functionals, a novel output feedback control strategy is

Output Tracking Control of Random Nonlinear Time-Varying Systems

open access: yesMathematics, 2022
This paper is concerned with the output tracking control problem for random nonlinear systems with time-varying powers. A distinct feature of this paper is that we consider time-varying powers and the second-order moment process simultaneously, which is ...

Nonlinear response of Q-boosting metasurfaces beyond the time-bandwidth limit

open access: yesNanophotonics, 2022
Resonant nanostructures, such as photonic metasurfaces, have created an unprecedented case for enhanced light–matter interactions through local field engineering. However, the presence of resonances fundamentally limits the bandwidth of such interactions.
