Adaptive Event-Triggered Finite-Time Tracking of Output-Constrained High-Order Nonlinear Systems with Time-Varying Powers.

Publication Type:Academic Journal

Source(s):Complexity. 7/7/2022, p1-15. 15p.

Abstract:This paper studies the adaptive event-triggered finite-time tracking of output-constrained high-order nonlinear systems with time-varying powers. Due to the presence of multiple unknown powers and the consideration of event-triggered control, all the e...

Dichotomy Condition and Periodic Solutions for Two Nonlinear Neutral Systems.

Publication Type:Academic Journal

Source(s):Journal of Function Spaces. 8/1/2022, p1-7. 7p.

Abstract:In this article, we consider two nonlinear neutral systems with multiple delays. Our main tool here is to use dichotomy theory to construct an implicit solution for these two systems. Utilizing Krasnoselskii's fixed point theorem, we obtain sufficient ...

Global Practical Conformable Stabilization by Output Feedback for a Class of Nonlinear Fractional‐Order Systems.

Publication Type:Academic Journal

Source(s):Mathematical Problems in Engineering. 6/24/2022, p1-10. 10p.

Abstract:Researchers have explored the concept of "practical stability" in the literature, pointing out that stability investigations always guarantee "practical stability" and the inverse is not true. The concept "practical stability" means that the origin is ...

A Stability Result for a Swelling Porous System with Nonlinear Boundary Dampings.

Publication Type:Academic Journal

Source(s):Journal of Function Spaces. 6/9/2022, p1-7. 7p.

Abstract:In this work, we consider a swelling porous system where the damping terms are on the boundary. We establish an explicit and general decay result, without imposing restrictive growth assumption near the origin on the damping terms. Our result allows a ...
