Robust Identification of Transient Port Responses Using Time Domain Orthonormal Vector Fitting
نویسندگان
چکیده
A robust technique is presented for parametric identification of linear time-invariant systems in the time domain. Based on a Sanathanan-Koerner iteration, the transfer function coefficients are calculated iteratively by minimizing a weighted linear cost function. The time-domain equivalent of the Muntz-Laguerre basis is used to improve the numerical conditioning of the associated system equations. It is shown that the method is computationally efficient, and able to fit highly dynamic responses. Copyright c © IFAC 2007

Broadband macromodelling of passive components using orthonormal vector fitting
Vector fitting is widely accepted as a robust macromodelling tool for efficient frequency domain identification of passive components. The orthonormal vector fitting technique is introduced, which improves the numerical stability of the method, by using orthonormal rational functions. This leads to better conditioned equations, reduces the numerical sensitivity to the choice of starting poles s...

متن کاملFrequency domain analysis of transient flow in pipelines; application of the genetic programming to reduce the linearization errors
The transient flow analyzing by the frequency domain method (FDM) is computationally much faster than the method of characteristic (MOC) in the time domain. FDM needs no discretization in time and space, but requires the linearization of governing equations and boundary conditions. Hence, the FDM is only valid for small perturbations in which the system’s hydraulics is almost linear. In this st...
