Data-driven LPV Control for Micro-disturbance Rejection in a Hybrid Isolation Platform
Alireza Karimi, Elias Sebastian Klauser
A novel approach for linear parameter-varying (LPV) controller synthesis for adaptive rejection of time-varying sinusoidal disturbances is proposed. Only the frequency response data of a linear time-invariant (LTI) multiple-input multiple-output (MIMO) sys ...
2024Improving Deepfake Detectors against Real-world Perturbations with Amplitude-Phase Switch Augmentation
Touradj Ebrahimi, Yuhang Lu, Ruizhi Luo
In recent years, the remarkable progress in facial manipulation techniques has raised social concerns due to their potential malicious usage and has received considerable attention from both industry and academia. While current deep learning-based face for ...
2023Frequency-domain data-driven position-dependent controller synthesis for Cartesian Robots
Alireza Karimi, Philippe Louis Schuchert
Cartesian robots have position-dependent dynamics that should be accounted for in high performance applications. Traditional methods design Linear Time Invariant (LTI) controllers which are robustly stable with respect to position variations, but require a ...
2022GNSS/INS Kalman Filter Integrity Monitoring with Uncertain Time Correlated Error Processes
Safety-critical navigation applications require that estimation errors be reliably quantified and bounded. Over the last decade, significant effort has been put to guarantee a bounded position estimation by using Global Navigation Satellite Systems (GNSS) ...
EPFL2022Study on the cross-correlation of GNSS signals and typical approximations
Pierre-André Farine, Cyril Botteron, Jérôme Leclère
In global navigation satellite system (GNSS) receivers, the first signal processing stage is the acquisition, which consists in detecting the received GNSS signals and determining the associated code delay and Doppler frequency by means of correlations wit ...
Springer Verlag2017Saturation of the response to stochastic forcing in two-dimensional backward-facing step flow: A self-consistent approximation
François Gallaire, Vladislav Mantic Lugo
Selective noise amplifiers are characterized by large linear amplification to external perturbations in a particular frequency range despite their global linear stability. Applying a stochastic forcing with increasing amplitude, the response undergoes a st ...
Amer Physical Soc2016Distributed Sensing of Signals Linked by Sparse Filtering
Martin Vetterli, Olivier Roy, Yue Lu, Ali Hormati
We consider the task of recovering correlated vectors at a central decoder based on fixed linear measurements obtained by distributed sensors. A general formulation of the problem is proposed, under both a universal and an almost sure reconstruction requir ...
2009Parts-Based Face Verification using Local Frequency Bands
In this paper we extend the Parts-Based approach of face verification by performing a frequency-based decomposition. The Parts-Based approach divides the face into a set of blocks which are then considered to be separate observations, this is a spatial deco ...
Springer2009A new technique for high-resolution frequency domain optical coherence tomography
Frequency domain optical coherence tomography (FDOCT) is a new technique that is well-suited for fast imaging of biological specimens, as well as non-biological objects. The measurements are in the frequency domain, and the objective is to retrieve an arti ...
