Design and circuit implementation of a conjugate Lü chaotic system

In order to generate complex attractor of chaos, a new chaotic system is constructed chaos based on a presented chaotic system. The system constructed in this paper combines with the presented chaotic system to form a switchable chaotic system. The switchable chaotic system can change its behavior automatism from one to another via a switch selector. The system is implemented based on FPGA by EDA technology, experiment shows a good agree with simulation.
