Seminar “Compressed Sensing and Discrete Optimization, parts I and II”

Speaker: Marc Pfetsch (Research Group Optimization, Dept. of Mathematics, Technische Universität Darmstadt)
When: WEDNESDAY, June 14th, 2017 — 11:00 – 13:00
Where: Meeting Room DISIM, Alan Turing building (Coppito 0).
Title: Compressed Sensing and Discrete Optimization, parts I and II

Abstract: The goal of these talks is to give an overview on compressed sensing from a discrete optimization/geometry point of view. The main problem in compressed sensing – the sparse representation problem – is to find the sparsest solutions of underdetermined linear equation systems. This problem is computationally hard, but can be efficiently solved by a linear program if certain conditions are satisfied. The talk will review some well known conditions and show that they are computationally hard to check. Moreover, the solution of this problem to global optimality will be discussed. The next step consists of presenting results on the unique recovery of integer solutions. Of course, even obtaining some feasible solution is hard in this case. Nevertheless, the potential of investing computational resources to obtain optimal solution will be discussed.

Seminar “Stability of interconnected uncertain delay systems: a converse Lyapunov approach”

Speaker: Dr. Ihab Haidar (ENSEA-Cergy, France, Laboratoire QUARTZ)
When: Monday, January 23rd, 2017 — 3:30pm
Where: ROOM A1.5, Alan Turing building (Coppito 0).
Title: Stability of interconnected uncertain delay systems: a converse Lyapunov approach

Abstract: This talk is interested by the asymptotic stability of interconnected uncertain delay systems. First, a collection of converse Lyapunov-Krasovskii theorems for uncertain linear delay systems, recently developed in the literature, is presented. The originality of these theorems resides in the weakly-degenerate conditions required on the Lyapunov-Krasovskii funcionals. Then, thanks to these theorems, sufficient conditions for stability of interconnected uncertain linear delay systems are presented.

American Model Predictive Control Summer School 2017

A four-day, eight-speaker American Summer School on Model Predictive Control (MPC) has been organized by Sasa V. Rakovic, James B. Rawlings and Ilya V. Kolmanovsky. The first American Summer School of MPC will be held at the University of Wisconsin-Madison from July 25, 2017 to July 28, 2017.

The American Summer School on MPC aims to enable up to 40 graduate students (as well as interested researchers and control practitioners) from a cross-cutting set of disciplines in engineering, science, and applied mathematics to receive advanced education and training from international experts in the theory, implementation and application of MPC. The instructors comprise leading researchers from universities, government laboratories, and industrial companies, and they have been selected for their leading expertise in the different research areas, as well as a diversity of backgrounds and disciplines in engineering, science and applied mathematics.

The main topics of the summer school are:

  • Introduction to MPC and MPC essentials (by William S. Levine).
  • Classical MPC: regulation, estimation, and disturbance models (by James B. Rawlings).
  • Robust MPC (by Sasa V. Rakovic).
  • Stochastic MPC (by Ilya V. Kolmanovsky).
  • Economic MPC (by David Angeli).
  • MPC for sampled-data systems (by Fernando Fontes).
  • Online optimization for MPC (by Lorenz T. Biegler).
  • Industrial applications of MPC (by Thomas A. Badgwell).

The summer school delivers a carefully crafted overview of the theoretical fundamentals of MPC, and it provides access to, and motivates the development of, freely-available and state-of-the-art numerical software for implementing the advanced MPC methods on difficult and challenging examples and industrial applications. The summer school also anticipates inclusion of class mini-projects that enable all attendees to present, and discuss, problems of direct interest to their research, and also to receive feedback from a set of instructors with valuable expertise in all areas of MPC research.

Additional information, including a detailed summer school schedule and registration information will be made available shortly at the summer school website www.che.wisc.edu/mpc-summer-school

The organizers of the summer school are grateful to NSF for providing financial support for up to 40 attending participants. Travel expenses will be reimbursed up to $500 pending final approval of NSF funding. A modest registration fee of $150 is also required for all attendees. Registration will open on May 1, and is on a first-come, first-served basis. Registration is capped at 40 students, so early registration is encouraged.

International Graduate School on Control (EECI-IGSC-2017)

The European Embedded Control Institute (EECI) is founded in 2006 in the framework of the HYCON Network of Excellence (FP6-IST-511368), a funded EC project from September 2004 to September 2008. EECI is a “lightweight” association (under the French Association Law 1901), based on volunteer work by its members. The EECI offers a legal structure for the Knowledge Community of Networked and Embedded Control.

Since the creation of EECI, IGSC Program is organized every year where independent modules on different topics of networked and embedded control are taught, one 21-hours module per week.

Our department will be hosting the Module M14 “Modeling, analysis and design of wireless sensor and actuator networks”, held by Carlo Fischione (KTH, Stockholm) and Alessandro D’Innocenzo (University of L’Aquila) from April 18th to April 21th 2017.

Please note that the deadline for advanced registration is coming soon (December 28th 2016).

Seminario: On stability of time-inhomogeneous Markov jump linear systems

Si comunica che il giorno Mercoledì 7 Dicembre alle ore 17.00 presso l’aula Aula A1.5 (Coppito 0),  il dottorando Yuriy Zacchia Lun terrà un seminario dal titolo:

On stability of time-inhomogeneous Markov jump linear systems

 

Abstract: Discrete-time time-inhomogeneous (DTTI) Markov jump linear systems (MJLS) are linear systems subject to abrupt parameter changes, with modal transitions governed by a DTTI finite-state Markov chain. This type of Markov chain has time-varying transition probability matrix, with variations, that are arbitrary within a polytopic set of stochastic matrices. Such mathematical model is especially important for wireless networked control systems, since it allows us jointly take into account the dynamics of a physical plant and nonidealities of wireless communication. In this seminar, we present necessary and sufficient conditions for mean square stability (MSS) of DTTI MJLS affected by polytopic uncertainties on transition probabilities. The aforementioned conditions require to decide whether the joint spectral radius (JSR) of a finite family of matrices is smaller than 1. Additionally, we prove that deciding MSS on DTTI MJLS is NP-hard and that MSS is equivalent to exponential mean square stability (EMSS) and to stochastic stability (SS).

Il tempo restante, dopo la presentazione, sarà dedicato a domande ed approfondimenti. A tal proposito vi chiedo di diffondere questo avviso a chi pensate possa essere interessato.

Lo stesso lavoro verrà presentato la settimana successiva al: “55th IEEE Conference on Decision and Control (CDC 2016)” a Las Vegas.

La durata della presentazione sarà di circa 20 minuti e si avrà tempo per eventuali domande, feedbacks e chiarimenti alla fine.
