Trajectory optimisation in space mechanics with Julia
Jean-Baptiste Caillau, Olivier Cots, Alesia Herasimenka
What it's about
- Nonlinear optimal control of ODEs:
\[g(x(t_0),x(t_f)) + \int_{t_0}^{t_f} f^0(x(t), u(t))\, \mathrm{d}t \to \min\]
subject to
\[\dot{x}(t) = f(x(t), u(t)),\quad t \in [t_0, t_f]\]
plus boundary, control and state constraints
- Our core interests: numerical & geometrical methods in control, applications
OptimalControl.jl for trajectory optimisation
Wrap up
- High level modelling of optimal control problems
- Efficient numerical resolution coupling direct and indirect methods
- Collection of examples
Future
- New applications (biology, space mechanics, quantum mechanics and more)
- Additional solvers: direct shooting, collocation for BVP, Hamiltonian pathfollowing...
- ... and open to contributions!
control-toolbox.org
- Open toolbox
- Collection of Julia Packages rooted at OptimalControl.jl
