Hybrid algorithm for compact and stable macromodelling of parameterised frequency responses

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 sensitivity analysis.
