@ocots @jbcaillau I tried various ways to initialize the orbital transfer problem, but I couldn't find one where the logarithm doesn't become negative. I also tried to start the indirect resolution by following the Kepler example, but I'm not sure if that's the right approach. |

@YouriRenoud if you have some difficulties you can switch to this issue: #28 |
|
@YouriRenoud pour aider à la convergence ne pas hésiter à jouer sur la taille de la discrétisation. Mettre 100, 500, 1000, 2000 points pour voir. |

@YouriRenoud pour initialiser :
|

@ocots @jbcaillau I finally could solve the minimal conso problem what are you thinking of this solution ? |
|
Can you plot the norm of the control? See the plot documentation. You can plot also in 3D, see the end of the Kepler application. |
|
For the 3D plot I only get one revolution before it stops ? |
hi @YouriRenoud cannot see the plot of the norm. for a strong enough log penalty and a large enough final time (20% larger than min time, e.g.), you should see a control subarc close to a zero arc (= zero norm) |

Todo:

@ocots @jbcaillau Here the norm of the control with the continuation of epsilon at the last iteration : |
nice @YouriRenoud can you please add (on the same plot) control norms for previous values of |
|
@YouriRenoud Can you please make a point on what you still have to do? |
|
@ocots The direct part is all finished and working but I am stuck in the indirect resolution and I don't know how to solve my problems. For example if I start two times the indirect resolution without changing anything the two solution won't give the same trajectory and it is not even close. Maybe I should start the other part of regularization with the Malisani's code ? |
@YouriRenoud Actually, writing the shooting function for the minimum consumption problem is not easy. Since, I won't be there before you finish, I think you should switch to Malisani's regularization. You can create another file for the tutorial. |
|
@jbcaillau I could plot this figure is that what you were expecting ? |
|
@YouriRenoud exactly: very nice! 👍🏽 |
|
Cette solution est bien celle pour temps fixé ? @YouriRenoud |
|
@antoinepichon03 oui c'est de la conso min |
