Hybrid algorithm for compact and stable macromodelling of parameterised frequency responses Vrije Universiteit Brussel Ghent University
A novel hybrid technique for the macromodelling of parameterised frequency responses is presented. A more compact model representation is proposed that guarantees stability of the poles by construction. It is shown that accurate parametric macromodels can be calculated using a reduced amount of model coefficients and data samples. The obtained macromodels can be used for efficient real-time design space exploration, design optimisation and ...
Fast parametric macromodeling of frequency responses using parameter derivatives Vrije Universiteit Brussel Ghent University
This letter presents a generalization of the multivariate Vector Fitting technique that includes parameter derivatives in the macromodellng process. The computational cost to simulate partial derivatives in terms of the parameters is often substantially lower than the simulation cost of additional data samples. An example shows that the inclusion of derivatives can be useful to reduce the required amount of data samples, while preserving the ...
