In this paper, we further study the dynamic characteristics of the Yuâ??Wang chaotic system obtained by Yu and Wang in 2012. The\nsystem can show a four-wing chaotic attractor in any direction, including all 3D spaces and 2D planes. For this reason, our interest\nis focused on multistability generation and chaotic FPGA implementation. The stability analysis, bifurcation diagram, basin of\nattraction, and Lyapunov exponent spectrum are given as the methods to analyze the dynamic behavior of this system. The\nanalyses show that each system parameter has different coexistence phenomena including coexisting chaotic, coexisting stable\nnode, and coexisting limit cycle. Some remarkable features of the system are that it can generate transient one-wing chaos,\ntransient two-wing chaos, and offset boosting. These phenomena have not been found in previous studies of the Yuâ??Wang chaotic\nsystem, so they are worth sharing. Then, the RK4 algorithm of the Verilog 32-bit floating-point standard format is used to realize\nthe autonomous multistable 4D Yuâ??Wang chaotic system on FPGA, so that it can be applied in embedded engineering based on\nchaos. Experiments show that the maximum operating frequency of the Yuâ??Wang chaotic oscillator designed based on FPGA\nis 161.212 MHz.
