Abstract :
In order to improve randomicity of chaos system, A novel switched chaotic model is presented based on Lorenz system by modifying the third equation´s product. The system consists of three chaotic subsystems and can change its behavior random among of the two or three subsystems via selector. The switchable system makes up of four switchable chaos subsystems. Some of its basic dynamical properties are studied detailedly, such as the feature of equilibrium, the phase portraits of hyperchaotic attractor, the Lyapunov exponexnt and the fractal dimension. Furthermore, A practical circuit is designed to realize the systems obtained based FPGA by EDA technology. It shows good agree with the simulation.
