On Delay-independent Stability of a class of Nonlinear Positive Time-delay Systems

TL;DR

This paper establishes a condition for delay-independent stability in a class of nonlinear positive systems, broadening the scope beyond monotone systems and including non-cooperative nonlinear systems.

Contribution

It introduces a new stability criterion applicable to nonlinear positive systems that are not necessarily monotone, extending existing results to a wider class of systems.

Findings

Provides a delay-independent stability condition for nonlinear positive systems.

Extends stability analysis to non-monotone systems.

Broadens applicability beyond cooperative systems.

Abstract

We present a condition for delay-independent stability of a class of nonlinear positive systems. This result applies to systems that are not necessarily monotone and extends recent work on cooperative nonlinear systems.
