“…[24,[26][27][28][29], Leung and Kuang [30], Mielke and Holmes [31], Tong et al [32,33], Koiller [34], and Ziglin [35] amongst many others. Based on the work of Wiggins and Shaw [36], Kuang et al [24,26] obtained the Melnikov integral of chaotic rotational dynamics of the gyrostat under the action of small perturbation torques, in the form of damping torques plus periodic moments. Certain interesting models on the nonlinear dynamics of dynamical systems may be found in Wittenburg [37], Heijden and Thompson [38], Thompson and Stewart [39], Hagedorn [40], Chen and Leung [41], and Davies and Moon [42] amongst others.…”
