A novel memristive chaotic circuit is presented, which is derived from the classical Chua’s circuit by substituting Chua’s diode with a first-order memristive diode bridge. The dynamical characteristics with the variations of circuit parameters are investigated both theoretically and numerically. The research results indicate that this circuit has three determined equilibrium points and displays complex nonlinear phenomena including coexisting bifurcation modes and coexisting attractors. Specifically, with another parameter setting, the memristive Chua’s circuit can generate hidden attractors and coexisting hidden attractors in a narrow parameter region. The phenomena of self-excited attractors and hidden attractors are experimentally captured from a physical circuit, which verify the numerical simulations.
