A Novel Megastable Oscillator with a Strange Structure of Coexisting Attractors: Design, Analysis, and FPGA Implementation

Figure 1

Coexisting limit cycles in System (1) resulted from random initial conditions distributed around the x-axis. Islands of attractors can be observed, consisting of 3, 4, and 5 limit cycles. Surprisingly 11 islands are enclosed by a huge limit cycle. The transients are shown in cyan, and steady states are shown in dark blue.
