H2 Optimal Approximation
model order reduction by interpolation of the Volterra series representation of the system's transfer function

    Statements

    This approach is based on the interpolation of the Volterra series representation of the system's transfer function and gives a local H2-optimal approximation, because the interpolation is chosen so that the system satisfies the necessary H2-optimality conditions upon convergence of the algorithm. Note that H2 stands for Hardy space.
