A memristive chaotic system is proposed, which has the properties of conditional symmetry, attractor growing and amplitude frequency control. The introduced sinusoidal function wins its conditional symmetry giving coexisting chaotic attractors while the tangent function realizes attractor self-reproducing in other two dimensions. Due to the two periodic functions, three regimes of attractor growing are found, where the polarity of each cell remains the same or switches from negative to positive. More significantly, the period of the tangent function realizes amplitude and frequency control in a certain circumstance. Analog circuit simulation proves the theoretical and numerical analysis.
