Abstract: In this paper, an uncertain fractional switched system is a fractional switched system disturbed by subjective uncertainty, which can be written by Caputo type of uncertain fractional differential equations. Few results concerning uncertain fractional systems were published before. To fill this gap, the property of solutions to uncertain fractional switched systems with finite-time horizon is investigated in depth. Based on two conditions called linear growth condition and Lipschitz condition, an existence and uniqueness theorem of solutions is proposed for the uncertain fractional switched systems, and the strict demonstration is given for the theorem in terms of uncertainty theory and Banach fixed point theorem. Finally, an uncertain stock model is proposed and analyzed to illustrate the effectiveness of the results obtained.
