Weighted Null-Space Fitting for Identification of Cascade Networks
Miguel Galrinho, Riccardo Prota, Mina Ferizbegovic +1
For identification of systems embedded in dynamic networks, applying the prediction error method (PEM) to a correct tailor-made parametrization of the complete network provided asy…
Estimating Models with High-Order Noise Dynamics Using Semi-Parametric Weighted Null-Space Fitting
Miguel Galrinho, Cristian R. Rojas, Hakan Hjalmarsson
Standard system identification methods often provide inconsistent estimates with closed-loop data. With the prediction error method (PEM), this issue is solved by using a noise mod…
Parametric Identification Using Weighted Null-Space Fitting
Miguel Galrinho, Cristian R. Rojas, Hakan Hjalmarsson
In identification of dynamical systems, the prediction error method using a quadratic cost function provides asymptotically efficient estimates under Gaussian noise and additional…
Optimal model order reduction with the Steiglitz-McBride method for open-loop data
Niklas Everitt, Miguel Galrinho, Håkan Hjalmarsson
In system identification, it is often difficult to find a physical intuition to choose a noise model structure. The importance of this choice is that, for the prediction error meth…
ARX modeling of unstable linear systems
Miguel Galrinho, Niklas Everitt, Håkan Hjalmarsson
High-order ARX models can be used to approximate a quite general class of linear systems in a parametric model structure, and well-established methods can then be used to retrieve…
