Abstract

Multi-dimensional uncertain differential equation is used to model a multi-dimensional dynamic uncertain system. In order to describe the influence of the initial value on the solution, this paper proposes a concept of stability for multi-dimensional uncertain differential equation. A sufficient condition is derived for a multi-dimensional uncertain differential equation being stable, and its effectiveness is illustrated by some examples. In addition, this paper shows that the given condition is not necessary for a multi-dimensional uncertain differential equation being stable via a counterexample. The results presented in this paper could be used to study the stability of multi-factor uncertain differential equations and high-order uncertain differential equations.
