To keep up with the ever increasing demand on performance and efficiency of control systems, accurate models are needed. System identification is concerned with the estimation and validation of mathematical models of dynamical systems from experimental data. The main problem considered in this thesis is how to take advantage of structural information in system identification. Including this additional information can significantly improve the quality of the identified model.First, the problem…

A new method for estimating the nonparametric time-variant frequency response function (TV-FRF) and its variance of a hybrid time-varying system is proposed and can achieve high estimation accuracy and small uncertainty without requiring prior knowledge of the time variation of system dynamics.


On optimal input design in system identification for control
Insight is provided in the potentials of this approach by finite impulse response model examples, for which it is possible to analyze the optimal input problem and show how the control specifications directly affect the excitation conditions in the system identification experiment.
Using Structural Information in System Identification
Recent advances in small and cheap communication and sensing have opened up for large scale systems with intricate interconnections and interactions. These applications pose new challenges for
Complexity Issues, Validation and Input Design for Control in System Identification
This thesis investigates why system identification, despite this rather pessimistic observation, is successfully applied in the industrial practise as a reliable modelling tool and connects prediction-erroridentification methods and robust control theory.

This contribution considers the problem of realizing an input signal with a desired autocorrelation sequence satisfying both input and output constraints for the system it is to be applied to. This
Identification for control: adaptive input design using convex optimization
An adaptive method for the direct design of FIR filters for the input spectrum design problem is developed and it is shown that this problem may be formulated as a convex optimization problem with linear matrix inequality constraints.
