Fixed-Order Robust Controller Design by Convex Optimization Using Spectral Models

This thesis proposes a new method to design fixed-order controllers in frequency domain using convex optimization. The method is based on the shaping of open-loop transfer function in the Nyquist diagram with infinity norm constraints on weighted closed-lo ...

Robust Controller Design by Convex Optimization based on Finite Frequency Samples of Spectral Models

Alireza Karimi, Roland Longchamp, Gorka Galdos Sanz de Galdeano

Some frequency-domain controller design problems are solved using a finite number of frequency samples. Consequently, the performance and stability conditions are not guaranteed for the frequencies between the frequency samples. In this paper, all possible ...

Fixed-order H-infinity Controller Design for Nonparametric Models by Convex Optimization

Alireza Karimi, Gorka Galdos Sanz de Galdeano

A new approach for robust fixed-order H-infinity controller design by convex optimization is proposed. Linear time-invariant single-input single-output systems represented by nonparametric models in the frequency domain are considered. It is shown that the ...

Spectral element approximation of the incompressible Navier-Stokes equations in a moving domain and applications

Gonçalo Pena

In this thesis we address the numerical approximation of the incompressible Navier-Stokes equations evolving in a moving domain with the spectral element method and high order time integrators. First, we present the spectral element method and the basic to ...

Store-and-forward based methods for the signal control problem in large-scale congested urban road networks

The problem of designing network-wide traffic signal control strategies for large-scale congested urban road networks is considered. One known and two novel methodologies, all based on the store-and-forward modeling paradigm, are presented and compared. Th ...

Experimental investigation into localized instabilities of mixed Rayleigh-Benard-Poiseuille convection

Peter Monkewitz, Emeric Grandjean

The stability of the Rayleigh-Benard-Poiseuille flow in a channel with large transverse aspect ratio (ratio of width to vertical channel height) is studied experimentally. The onset of thermal convection in the form of 'transverse rolls' (rolls with axes p ...

Experimental investigation into localized instabilities of mixed Rayleigh-Bénard-Poiseuille convection

Emeric Grandjean

An experimental study of the stability of the Rayleigh-Bénard-Poiseuille flow was performed in a large transverse aspect ratio channel. The onset for the transverse thermo-convective rolls was determined as a function of the Reynolds number for two differe ...

Analysis of UWB antennas for carrier-based UWB impulse radio

Anja Skrivervik, Gabriela Quintero Diaz De Leon

A Carrier-based UWB pulse is compared with the commonly used Gaussian pulse. Two antenna systems are simulated and measured in frequency domain. The impulse response and the Power Spectral Density (PSD) of both studied pulses are obtained. The effect of ea ...

Auto-ajustement de régulateurs PID robustes dans le domaine fréquentiel

Daniel Garcia

This work considers the adjustment of proportional-integral-derivative (PID) controllers. Because of their very simple structures, this kind of controllers are very appreciated, and used abundantly by the industrial community. The restricted number of the ...
