摘要：
The memristor-based chaotic systems are more and more popular with academia because of their abundant dynamics. This paper constructs a novel 4D chaotic system by introducing a flux-controlled memristor into the existing Sprott-J system. Dynamic behaviors of the system are studied by theoretical analysis and numerical simulations. It surprisingly shows that the system can yield infinite coexisting attractors via changing the initial values. And the amplitudes of all signals can be controlled by adjusting a certain parameter. The circuit and microcontroller realization is given as well; corresponding results agree well with numeral simulations.
