Abstract

In this paper, robust adaptive control  for uncertain fractional-order financial chaotic systems with bounded unknown external disturbance is studied. By utilizing the fractional-order extension of the classical Lyapunov stability methods, an adaptive controller is presented for controlling fractional-order financial  chaotic system.  Quadratic Lyapunov function is employed in the stability analysis, and fractional-order adaptation laws  are designed to update controller parameters online.
The proposed controller  can ensure that  the system states converge to the origin asymptotically and all signals in the closed-loop system remain bounded.  Finally, simulation results are presented to confirm our theoretical
results.
