OptimalControl.jl
The OptimalControl.jl package is the root package of the control-toolbox ecosystem. The control-toolbox ecosystem gathers Julia packages for mathematical control and applications. It aims to provide tools to model and solve optimal control problems with ordinary differential equations by direct and indirect methods.
Installation
To install OptimalControl.jl, please open Julia's interactive session (known as REPL) and use the Julia package manager:
using Pkg
Pkg.add("OptimalControl")
Basic usage
Let us model, solve and plot a simple optimal control problem.
using OptimalControl
using NLPModelsIpopt
using Plots
ocp = @def begin
t ∈ [0, 1], time
x ∈ R², state
u ∈ R, control
x(0) == [ -1, 0 ]
x(1) == [ 0, 0 ]
ẋ(t) == [ x₂(t), u(t) ]
∫( 0.5u(t)^2 ) → min
end
sol = solve(ocp)
plot(sol)
- For more details about this problem, please check the basic example tutorial.
- For a comprehensive introduction to the syntax used above to describe the optimal control problem, check the abstract syntax tutorial.
- The
solve
function has options, see the solve tutorial. - You can customise the plot with the
plot
function, see the plot tutorial.
