Abstract

A new method to numerically solve trajectory optimization problems is developed. The method uses direct transcription to convert the continuous optimal control problem into a parameter optimization problem that can be solved with non-linear programming. A high-order Taylor series expansion about each node is used to convert the system equations into algebraic constraint equations. Automatic differentiation is used to compute the derivatives of the system equations required to keep arbitrarily many terms in the Taylor series. Several orbit transfer problems are solved to evaluate the performance of the new method.
