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

Figure 4

Coexisting attractors in System (2) resulted from random initial conditions distributed around the x-axis. The transients are shown in cyan, and steady states are shown in dark blue. The frequency of the forcing term is , and the amplitude is (a) , (b) , and (c) . Increasing the amplitude of the forcing term leads to more overlapped islands.
