In this paper, from the perspective of the physical mechanism of chaos, multi-scroll chaotic attractors with multi-wing have been generated via oscillatory potential wells. The potential wells are produced by saddle-node bifurcation, which are multiplied by the oscillation factor to get the oscillation potential wells. The Duffing equation can describe the motion of a particle in the oscillatory potential well. The shape of the potential well significantly affects the movement of the particle,

The oscillatory potential well can cause the mass points in it to move chaotically, which can be considered as a physical mechanism of chaos generation. Based on this physical mechanism, the oscillatory multi-well potential with multi-concave is used to generate controllable multi-scroll chaotic attractors with multi-wing. These attractors have two kinds of topological units: scroll and wing. The topological structure of the attractor depends on the shape of the potential well, that is, the wells and the concaves correspond to the scrolls and wings of the attractor. By constructing potential w...
