1. Frequency Domain Identification of Continuous-Time Systems : Reconstruction and Robustness
Abstract : Approaching parameter estimation from the discrete-time domain is the dominating paradigm in system identification. Identification of continuous-time models on the other hand is motivated by the fact that modelling of physical systems often take place in continuous-time. READ MORE

2. On the Frequency Domain Analysis of Nonlinear Systems
Abstract : In this report we study how the Volterra series description of nonlinear systems can be applied to some different problems.We study oscillations in nonlinear systems. READ MORE

3. Multivariable Frequency-Domain Identification of Industrial Robots
Abstract : Industrirobotar är idag en väsentlig del i tillverkningsindustrin där de bland annat används för att minska kostnader, öka produktivitet och kvalitet och ersätta människor i farliga eller slitsamma uppgifter. Höga krav på noggrannhet och snabbhet hos robotens rörelser innebär också höga krav på de matematiska modeller som ligger till grund för robotens styrsystem. READ MORE

4. Frequency Domain Linearized Navier-Stokes Equations Methodology for Aero-Acoustic and Thermoacoustic Simulations
Abstract : The first part of the thesis focuses on developing a numerical methodology to simulate the acoustic properties of a hybrid liner consisting of a perforated plate, a porous layer and a Helmholtz cavity. Liners are always a standard way to reduce noise in today’s aeroengines, e.g. READ MORE
