STK 11.2: perform a low-thrust optimal transfer

Websolution to the optimal control problems arising from a low-thrust transfer between asteroids subject to short transfer times (i.e. transfers not requiring multiple revolutions around the Sun). Our work is mainly motivated to refine search methods in multiple asteroid rendezvous problems such as the ones described in the 7th edition of the GTOC. WebIn this article, low-thrust propulsion refers to EP only, unless noted otherwise. During the optimization of CP trajectories only a finite and small number of variables have to be considered, namely the number, magnitude and direction of the impulses. WebA new technique is developed to optimize continuous medium- and low-thrust orbit transfers. This approach combines large-scale linear programming algorithms with discretization of the trajectory dynamics on segments and a set of pseudoimpulses or control for each segment.
