This paper presents the use of Legendre pseudospectral
method for the optimization of finitethrust orbital transfer for
spacecrafts. In order to get an accurate solution, the Systems
dynamics equations were normalized through a dimensionless method.
The Legendre pseudospectral method is based on interpolating
functions on LegendreGaussLobatto (LGL) quadrature nodes. This
is used to transform the optimal control problem into a constrained
parameter optimization problem. The developed novel optimization
algorithm can be used to solve similar optimization problems of
spacecraft finitethrust orbital transfer. The results of a numerical
simulation verified the validity of the proposed optimization method.
The simulation results reveal that pseudospectral optimization method
is a promising method for realtime trajectory optimization and
provides good accuracy and fast convergence.
