Multistability Analysis and FPGA Implementation of a New 3D Chaotic System

In this paper, a new 3D chaotic system is proposed based on a generalized Hamiltonian system with dissipative term by selecting the appropriate structure matrix, dissipation matrix, and input matrix. The basic dynamic characteristics are analyzed by using simulation including phase portraits, Lyapunov exponent spectrum and bifurcation diagram. In addition, the coexisting attractors and multistability of the proposed system are further investigated. Finally, this new 3D chaotic system is validated by designing and implementing its digital circuit using the Field Programmable Gate Array (FPGA).
