Introducing SOSTOOLS: A general purpose sum of squares programming solver

S Prajna, A Papachristodoulou… - Proceedings of the 41st …, 2002 - ieeexplore.ieee.org
SOSTOOLS is a MATLAB toolbox for constructing and solving sum of squares programs. It
can be used in combination with semidefinite programming software, such as SeDuMi, to …

Nonlinear control synthesis by sum of squares optimization: A Lyapunov-based approach

S Prajna, A Papachristodoulou… - 2004 5th Asian control …, 2004 - ieeexplore.ieee.org
This paper addresses the state feedback control synthesis problems for nonlinear systems,
either without or with guaranteed cost or H/sub /spl infin// performance objectives. By …

Tuning the dials of synthetic biology

…, GBV Stan, A Papachristodoulou… - …, 2013 - microbiologyresearch.org
Synthetic Biology is the ‘Engineering of Biology’ – it aims to use a forward-engineering design
cycle based on specifications, modelling, analysis, experimental implementation, testing …

Positive forms and stability of linear time-delay systems

MM Peet, A Papachristodoulou, S Lall - SIAM Journal on Control and …, 2009 - SIAM
We consider the problem of constructing Lyapunov functions for linear differential equations
with delays. For such systems it is known that exponential stability implies the existence of a …

[HTML][HTML] Chordal decomposition in operator-splitting methods for sparse semidefinite programs

Y Zheng, G Fantuzzi, A Papachristodoulou… - Mathematical …, 2020 - Springer
We employ chordal decomposition to reformulate a large and sparse semidefinite program (SDP),
either in primal or dual standard form, into an equivalent SDP with smaller positive …

On the construction of Lyapunov functions using the sum of squares decomposition

A Papachristodoulou, S Prajna - Proceedings of the 41st IEEE …, 2002 - ieeexplore.ieee.org
A relaxation of Lyapunov's direct method has been proposed elsewhere that allows for an
algorithmic construction of Lyapunov functions to prove stability of equilibria in nonlinear …

Advanced methods and algorithms for biological networks analysis

…, S Prajna, A Papachristodoulou… - Proceedings of the …, 2006 - ieeexplore.ieee.org
Modeling and analysis of complex biological networks presents a number of mathematical
challenges. For the models to be useful from a biological standpoint, they must be …

Delay robustness in consensus problems

U Münz, A Papachristodoulou, F Allgöwer - Automatica, 2010 - Elsevier
We investigate the robustness of consensus schemes for linear Multi-Agent Systems (MAS)
to feedback delays. To achieve this, we develop a unified framework that considers linear …

A tutorial on sum of squares techniques for systems analysis

A Papachristodoulou, S Prajna - Proceedings of the 2005 …, 2005 - ieeexplore.ieee.org
This tutorial is about new system analysis techniques that were developed in the past few
years based on the sum of squares decomposition. We present stability and robust stability …

[HTML][HTML] Structural identifiability of dynamic systems biology models

…, A Barreiro, A Papachristodoulou - PLoS computational …, 2016 - journals.plos.org
A powerful way of gaining insight into biological systems is by creating a nonlinear differential
equation model, which usually contains many unknown parameters. Such a model is …
