Synchronization and FPGA realization of complex networks with fractional-order Liu chaotic oscillators

In this paper synchronization of fractional-order Liu chaotic oscillators is addressed. Two networks of fractional-order Liu chaotic oscillators are synchronized by appealing to results from complex systems theory for integer-order systems. We use and implement complex dynamical networks composed by nine Liu chaotic oscillators. Two scenarios are considered: (i) complex network with regular topology, and (ii) complex network with irregular topology. Synchronization of both complex networks is achieved by coupling the fractional-order chaotic oscillators through their second state. We use numerical simulations to verify the results, we also show an FPGA realization of the complex networks previously synchronized.
