Detailed Description

Numeric trim using finite differences.

Simple and robust Newton solver using central differences for Jacobian. Works with the existing double-typed Simulator without symbolic components.

Algorithm:

1. Evaluate residual F(u) = [selected derivatives]
2. Compute Jacobian J = dF/du via central differences
3. Newton step: u_new = u - damping * J^(-1) * F
4. Apply bounds (projection)
5. Repeat until ||F|| < tolerance

Solve()

icarus::staging::TrimResult icarus::staging::FiniteDifferenceTrim::Solve ( ::icarus::Simulator & sim, const TrimConfig & config )

inlineoverridevirtual

Solve trim problem.

Finds control values that zero the specified derivatives. Modifies the simulator's signal values to the trim solution.

Parameters

sim	Simulator to trim (will be modified)
config	Trim configuration

Returns

TrimResult with convergence info and final values

Implements icarus::staging::TrimSolver.
