【Abstract】 A model of two order cascading acousto-optic bistable system is constructed. The convergence behavior of the Lyapunov. exponents is given. Dynamics of the system is investigated by computing the evolution of the Lyapunov exponent spectrum versus various parameters. The bifurcation and the phase space diagrams are plotted. Numerical results show that the structure of the system variables plays an important role in the evolution form of Lyapunov exponent spectrum. Meanwhile, hyperchaos states are found.更多还原
