Parameters a = 4.2, b = 1, c = 2, IC = (0.1 − k, 0.1, 0.1), offset boosting in the x axis. (a) Time domain waveform when k takes typical values. (b) Attractors on the x–y plane when k takes typical values; (c) LE spectrum (top) and bifurcation diagram (bottom) in the range of k ∈ [− 10, 10]. (d) The mean values of each state over the interval k ∈ [− 10, 10].
