Currently I am working on a code that optimizes the flight path of an ascending rocket to a final orbit in terms of mass reduction. More precisely I would like my code to optimize my Equations of Motions so that it returns me a function alpha(t). Alpha(t) is a thrust vector control variable.

Which Optimizer should I use for that problem and why?

Hope you can help me out, thanks!

Can you please upload your code for the trajectory optimization.

Thank You

Hi,

this appears to be an optimal control problem. Consider to use Symbolic Math Toolbox - espacially have a look at the functionalDerivative function. If you set this expression equal to zero, it enables to get a function alpha(t) that optimizes the functional which describes your system. There are some examples given in the documentation - maybe this is the right choice to tackle your problem.

Best regards

Stephan
