This inverse modeling approach is part of the newly developed DLR Space Systems Library for objectoriented modeling and simulation of satellites and launchers in a detailed space environment. For satellites with flexible structures; the library provides models for normal simulation mode and the necessary tools to directly generate approximate inverse models.

In this paper; trajectory optimization is shown to be an important use case for inverse dynamic models. By inversion based reformulation of the trajectory optimization problem; the optimal reference motion of the control system can be determined in a reliable and efficient way.
