Influence of amplitude modulation parameter b when parameter a = 2, c = 2, and initial condition IC = (0.1, 0.1, 0.1). (a) Time domain waveform of x. (b) Time domain waveform of y. (c) Time domain waveform corresponding to z. (d) The mean of the absolute values of the three state variables. (e) Lyapunov exponential spectrum and bifurcation diagram of b in the interval [0.01, 2]; (f) an attractor in 3-dimensional phase space when b = 0.5, b = 1, b = 2.
