【Abstract】 The chaotic signal generated from circuit implementation has high-frequency property, which is significant in application of the chaos-based secure communication and liquid mixing et al. An electronic circuit has been designed to realize a new chaotic system reported up to date. The circuit implementation shows a good agreement between the computer simulations and the experimental results, which further verifies existence of the complex chaotic attractor. Meanwhile, it is pointed out the significant distinction of application between numerical simulation and circuit implementation due to their different frequencies. Finally, the synchronization of the new chaotic system is realized by using the single variable coupling feedback, and the circuit of synchronization has been designed.更多还原
