Low-Thrust Interplanetary Orbit Transfers Using Hybrid Method with Mutiple Shooting.pdf
A hybrid trajectory optimization method (HTOM) with multiple-shooting techniques has been developed and utilized to compute a variety of optimal low-thrust interplanetary orbit transfers. Unlike direct methods, HTOM employs the system Lagrange costate equations to govern the optimal control, which are derived from the two-point boundary-value problem and expressed by a set of equinoctial elements. HTOM converts the optimal control problem to the parameter optimization that in turn is solved by nonlinear programming. A flexible multiple-shooting technique is developed to greatly improve robustness of convergence. This method is capable of modeling multiple powered and coast arcs, planetary gravity assists,intermediate rendezvous, and realistic electric propulsion systems. The advantages of the HTOM include significant reduction in the design space, improved solution accuracy compared with direct methods, large convergence domain with the aid of multiple shooting,
