Level crossing sampling in feedback stabilization under data-rate constraints

E Kofman, JH Braslavsky - … of the 45th IEEE Conference on …, 2006 - ieeexplore.ieee.org
This paper introduces a novel event-driven sampled-data feedback scheme where the plant
output samples are triggered by the crossings-with hysteresis-of the signal through its …

A systematic method to obtain ultimate bounds for perturbed systems

E Kofman, H Haimovich, MM Seron - International Journal of …, 2007 - Taylor & Francis
In this paper, we develop a systematic method to obtain ultimate bounds for both continuous-
and discrete-time perturbed systems. The method is based on a componentwise analysis of …

Discrete event simulation of hybrid systems

E Kofman - SIAM Journal on Scientific Computing, 2004 - SIAM
This paper describes the quantization-based integration methods and extends their use to
the simulation of hybrid systems. Using the fact that these methods approximate ordinary …

Characterisation of interval-observer fault detection and isolation properties using the set-invariance approach

M Pourasghar, V Puig, C Ocampo-Martinez - Journal of the Franklin …, 2020 - Elsevier
The aim of this paper is to provide a robust Fault Detection and Isolation (FDI) approach that
combines the set-invariance approach with a zonotopic interval observer. The effect of the …

Muestreo, control y comunicación basados en eventos

S Dormido, J Sánchez, E Kofman - Revista Iberoamericana de Automática …, 2008 - Elsevier
Los sistemas de control periódicos o activados por tiempo han dominado casi de manera
exclusiva la investigación en ingeniería de control. El control basado en eventos es una …

Event-based control using quadratic approximate value functions

R Cogill - Proceedings of the 48h IEEE Conference on …, 2009 - ieeexplore.ieee.org
In this paper we consider several problems involving control with limited actuation and
sampling rates. Event-based control has emerged as an attractive approach for addressing …

[HTML][HTML] A third order discrete event method for continuous system simulation

E Kofman - Latin American applied research, 2006 - SciELO Argentina
This paper introduces a new numerical method for integration of ordinary differential
equations. Following the idea of quantization based integration, ie, replacing the time …

[图书][B] Set-theoretic fault-tolerant control in multisensor systems

F Stoican, S Olaru - 2013 - books.google.com
Fault-tolerant control theory is a well-studied topic but the use of the sets in detection,
isolation and/or reconfiguration is rather tangential. The authors of this book propose a …

Quantization-based simulation of differential algebraic equation systems

E Kofman - Simulation, 2003 - journals.sagepub.com
The author studies the use of first-and second-order quantized state systems methods (QSS
and QSS2) in the simulation of differential algebraic equation (DAE) systems. A general …

Quantization-based new integration methods for stiff ordinary differential equations

G Migoni, E Kofman, F Cellier - Simulation, 2012 - journals.sagepub.com
In this paper we introduce new classes of numerical ordinary differential equation (ODE)
solvers that base their internal discretization method on state quantization instead of time …
