Chaos control of a fractional-order financial system (Q1958813)

Summary: The fractional-order financial system introduced by \textit{W.-C. Chen} [``Nonlinear dynamics and chaos in a fractional-order financial system'', Chaos Solitons Fractals 36, No.~5, 1305--1314 (2008)] displays chaotic motions at order less than 3. In this paper we extend the nonlinear feedback control in ODE systems to fractional-order systems, in order to eliminate the chaotic behavior. The results are proved analytically by applying the Lyapunov linearization method and stability condition for fractional system. Moreover, numerical simulations are shown to verify the effectiveness of the proposed control scheme.
