Hammouch, Zakia; Mekkaoui, Toufik Chaos synchronization of a fractional nonautonomous system. (English) Zbl 1298.34093 Nonauton. Dyn. Syst. 1, 61-71 (2014). Summary: In this paper we investigate the dynamic behavior of a nonautonomous fractional-order biological system. With the stability criterion of active nonlinear fractional systems, the synchronization of the studied chaotic system is obtained. On the other hand, using a Phase-Locked-Loop (PLL) analogy we synchronize the same system. The numerical results demonstrate the efiectiveness of the proposed methods.
