Existence and Uniqueness of Positive Solutions for a Fractional Switched System
Keyword(s):
We discuss the existence and uniqueness of positive solutions for the following fractional switched system: (Dc0+αu(t)+fσ(t)(t,u(t))+gσ(t)(t,u(t))=0,t∈J=[0,1]);(u(0)=u′′(0)=0,u(1)=∫01u(s) ds), whereDc0+αis the Caputo fractional derivative with2<α≤3,σ(t):J→{1,2,…,N}is a piecewise constant function depending ont, andℝ+=[0,+∞), fi,gi∈C[J×ℝ+,ℝ+],i=1,2,…,N. Our results are based on a fixed point theorem of a sum operator and contraction mapping principle. Furthermore, two examples are also given to illustrate the results.
