Indirect optimal control package

Orekit development

Hi folks,

This message to let you know that on the develop branch, there is the beta version of a new package “control.indirect” meant for using the Pontryagin Maximum Principle with numerical propagation (and for now only with Cartesian coordinates, no matter if there is a central body or not)

Features are:

  • Adjoint dynamics for some common forces
  • A range of so-called energy-like cost function
  • A fixed time fixed boundary single shooting algorithm

It will be released with version 12.2 (in September?).
Please give me your feedback by then. I will add in the meantime a convenient way to evaluate the Hamiltonian.

Possible Devs for >=13.0 include more adjoint dynamics, cost functions and more shooting capabilities.

Cheers,
Romain

Thanks a lot, @Serrof, that’s great!!

I haven’t taken time to check and appreciate your work so far, but I’ll do it for sure in the future.
