Abstract

In order to get a good pseudo random sequence (used to spread spectrum communication and information encryption, etc), this paper introduces a variable structure chaotic system, which consists of four different subsystems and can change its structure timely and randomly from one to another using two switching functions. Study the basic dynamic characteristics, including symmetry, equilibrium, dissipativity, and Lyapunov exponent. Moreover, an analogue circuit is designed and realized.
