| Abstract: | This paper is concerned with analysis and study of minimum fuel coplanar transfer with finite thrust by applying Pontryagin maximum principle. The solution conditions for optimal trajectories and optimal controls are concerned. In order to reduce some difficulties involved in solving a two -point boundary value problem via adjoint variables, we discuss a non-linear programming method in which the direct use of transversality conditions is avoided. In this method according to the "adjoint-control" transformations the initial value of control variables is instead of the initiial value of adjoint variables. It makes the initial iterative variable more practical and easy to be determined. |
