The influence of couple strength m1 and m2 on the dynamic behavior of the system with fixed parameters a = 2.5, b = 0.5, c = 1.5, IC = (0.1, 0.1, 0.1, 0). (a) 2D maximum LE distribution diagram. (b) Periodic, quasi-periodic, and chaotic attractors corresponding to typical values of m1 and m2. (c) The LE spectrum and bifurcation diagram in m1 ∈ [0.3, 2]. (d) The LE spectrum and bifurcation diagram in m2 ∈ [0.3, 2].
