EOptInterface

decision_vars(sys)

Returns the decision variables for an optimization problem formulated from a ModelingToolkit system.

full_solution(model, sys)

Returns a dictionary of optimal solution values for the observed variables of an algebraic ModelingToolkit system if the JuMP model is solved.

register_nlsystem(model, sys, obj, ineqs)

Automatically formulates algebraic JuMP constraints and objective function from an algebraic ModelingToolkit system and user-provided constraints and objective symbolic expressions.

Arguments

• model::JuMP.Model: the JuMP model
• sys::ModelingToolkit.System: the ModelingToolkit system
• obj::Symbolics.Num: a symbolic expression of the objective function using the ModelingToolkit system variables
• ineqs::Vector{Symbolics.Num}: a vector of symbolic expressions of inequality constraints using the ModelingToolkit system variables

register_odesystem(model, sys, tspan, tstep, integrator)

Automatically applies forward transcription and registers the discretized ODE ModelingToolkit system as algebraic JuMP constraints.

Arguments

• model::JuMP.Model: the JuMP model
• sys::ModelingToolkit.System: the ModelingToolkit system
• tspan::Tuple{Real,Real}: the time span over which the dynamic model is simulated
• tstep::Real: the time step used in the integration scheme
• integrator::String: integration scheme used in discretization, "EE" for explicit Euler or "IE" for implicit Euler
