Bifurcation plots for preset angle, \(\alpha _{pre}(^\circ )\) = \(17.5^\circ\): (a) \(\overline{\omega }\) = 0.56 , (b) \(\overline{\omega }\) = 0.62, (c) \(\overline{\omega }\) = 0.67, (d)\(\overline{\omega }\) = 0.75, Regime (i) stable fixed point (FP) attractor, Regime (ii) coexisting stable FP and stable LCO attractors, and Regime (iii) stable LCO attractor, showing the subcritical Hopf bifurcation.
