| Outline of Final Research Achievements |
In the multi-body dynamics where analytical approach is difficult, we analyzed the trajectory using the control theory. We applied nonlinear control theory and proposed a control system that achieves engineering purpose such as disturbance suppression while utilizing the structure of dynamical system. The concept of attractive set, which is a set of initial states that can reach the desired state by low thrust continuous acceleration, is introduced on the basis of optimal control. It was clarified that the relationship between the optimally controlled trajectory with stable and unstable manifolds of dynamic system. In addition, we designed a transfer orbit between equilibrium points using stable and unstable manifolds and confirmed that fuel consumption is greatly reduced.
