Method for suppressing out-of-plane chaos of periodic perturbation induced rope-load system

The invention discloses a method for suppressing out-of-plane chaos of a periodic perturbation induced rope-load system, relates to the technical field of spacecraft flight, and particularly provides a method for identifying and suppressing chaos of out-of-plane rolling motion of the system induced under the action of periodic perturbation excitation for a space rope-load system. The method comprises the following steps: firstly, introducing an environmental perturbation factor which changes periodically, then converting an out-of-plane motion kinetic equation of a system into a dimensionless form, and then calculating an unstable equilibrium point and a heteroclinic orbit of the system by using an undisturbed Hamiltonian system; and then, whether the system will generate heterotaxis track cross intersection near a heterotaxis point under periodic excitation is researched through a Meivov function, so that the phenomenon of out-of-plane chaos of the system is identified, and finally, parameter adjustment is p
