Combining Krylov Subspace Method And Routh Approximation For Reduced Order Modelling
A combination of Krylov subspace method and Routh approximant method is presented to derive a reduced
order model. Krylov subspace method is used to derive a medium size model first for a large system then a reduced order
model using Routh approximation is derived as a second step.
