Dynamical Behaviors of A Modified Chua's Circuit

A modified Chua's circuit is implemented meminductor and the improved memristive diode bridge emulator in this paper. The state equations of the modified Chua's circuit are described. The dynamical behaviors such as equilibrium set, Lyapunov exponents and diagram are revealed by theoretical analysis and numerical simulations. Furthermore, the circuit exhibits rich dynamical behaviors including chaos, hyperchaos, periodic windows, period states, crisis scenarios and coexisting attractors. It is noted that coexisting attractors depend on the initial values and parameters of system. Furthermore, the simulation results demonstrate that some strange chaotic attractors such as double-scroll type and like butterfly attractor are displayed when parameter and initial value are changing.
