Dr. Petr Horáček from Rockwell Automation will have a talk on "Modeling and simulation of dynamical systems in industry". It has become sort of a tradition over the last few years to have his talk included among the lectures of our undergraduate course on modeling and simulation of dynamical systems at Cybernetics and Robotics undergraduate program. Due to the popularity of this talk among students we decided to organize this as regular seminar so that not only the undergrads but also grad students, postdocs and faculty members can attend it.

Petr Horacek is one of leading experts in Czech republic on modeling, simulation and advanced control of industrial processes and systems (and a former faculty member of department of control engineering at CTU in Prague). His portfolio includes projects from various applications domains such as  food processing industry (fiber glass production, cheese cooker, tunnel pasteurizer of beer, wet blender, chocolate tempering machine, tower dryer), waterworks industry (water distribution system for a big city agglomeration, complex pumping station, sewage system, desert irrigation system) and production processes (curing machine). Petr plans to give an overview of his industrial projects and is willing to discuss the details of any project that the audience find attractive. The key flavour of his modeling projects is that he insists on building the models from the first principles. The actual physical parameters might be determined from the measured data but the key structure of the model is assembled using the knowledge of the physics of the problem. Being one of the first promoters of power bond graphs in the Czech and Slovak engineering communities, his talk might be a confirmation that this methodology is perfectly practical and useful. After all, that is why we decided to base our own undergrad course on bond graphs...

Everyone is welcome to the lecture by Dr. Vishwesh V. Kulkarni. The talk will start at 2pm in the K14 seminar room of Department of Control Engineering FEL CVUT, Karlovo namesti 13/E in Prague. It will take one hour.

Abstract: Biology is the science of the century.  Life is an information-driven chemical process in which DNA encodes basic programs and creates systems to execute those. Here, the resulting molecular systems and actuators make decisions using molecular sensors. The problem of controlling such complex dynamical systems using limited amount of information has emerged as one of the most important challenges for science and technology. A control theoretic approach is useful in approaching a good enough solution to this problem. Indeed, as George Zames pointed out in 1966, the input-output stability theory aims and works towards facilitating qualitative assessments using only a coarse level system information that may be entirely devoid of any details on the internal structure of the given system. Here, the art is in extracting as much information as possible from the available data so that the conservatism in the characterization and control is minimized. This talk is broadly divided into two parts: (1) modeling of nonlinear systems using sparse datasets, and (2) a synthesis of nonlinear dynamical systems using biomolecular components. The first presents results on how compressive sensing ideas can be used to obtain nonlinear dynamical models using sparse omics datasets and highlights the efficiency of this approach using the benchmark synthetic data of Cantone et. al. (Cell 2009). The second part presents techniques and a software to synthesize nonlinear dynamical systems using chemical reactions and, in particular, using DNA and enzymes.

Bio: Dr. Vishwesh Kulkarni is a Visiting Assistant Professor at the Department of Electrical Engineering, University of Minnesota, Minneapolis. He received Ph.D. in Electrical Engineering from the University of Southern California in 2001 and was a postdoctoral researcher at the Massachusetts Institute of Technology, 2001-2003, and at the University of Colorado, Boulder, 2004-2005. He was a faculty at the Department of Electrical Engineering, Indian Institute of Technology Bombay, 2006-2010, and also served as a co-founder and the president of Sentina Systems, Boston, MA, 2005-2010. Along with Prof. Guy-Bart Stan (Imperial College) and Prof. Karthik Raman (IIT Madras), he is a co-editor of the book System Theoretic Approaches to Systems and Synthetic Biology which will be published by Springer Verlag in May 2014.

Everyone is welcome to a public lecture given by the world-renowned expert on methods for optimal control of cooperative multiagent systems - professor Frank Lewis. The talk will be given at K14 seminar room at Karlovo namesti 13/E (see http://aa4cc.dce.fel.cvut.cz/content/contact-information for the instructions on how to get there) and will start at 10am. It will take about one hour. After the talk there will be an opportunity to discuss scientific issues with the lecturer. The talk is given within the IEEE Control Systems Society Distinguished Lecturer Program (http://www.ieeecss.org/member-activities/distinguished-lecturers-program).

Abstract: Distributed systems of agents linked by communication networks only have access to information from their neighboring agents, yet must achieve global agreement on team activities to be performed cooperatively.  Examples include networked manufacturing systems, wireless sensor networks, networked feedback control systems, and the internet.  Sociobiological groups such as flocks, swarms, and herds have built-in mechanisms for cooperative control wherein each individual is influenced only by its nearest neighbors, yet the group achieves consensus behaviors such as heading alignment, leader following, exploration of the environment, and evasion of predators.  It was shown by Charles Darwin that local interactions between population groups over long time scales lead to global results such as the evolution of species.
Natural decision systems incorporate notions of optimality, since the resources available to organisms and species are limited. This talk investigates relations between the stability of cooperative control and optimality of cooperative control. 

Stability: A method is given for the design of cooperative feedbacks for the continuous-time multi-agent tracker problem (also called pinning control or leader-following) that guarantees stable synchronization on arbitrary graphs with spanning trees.  It is seen that this design is a locally optimal control with infinite gain margin.  In the case of the discrete-time cooperative tracker, local optimal design yields stability on graphs that satisfy an additional restriction based on the Mahler instability measure of the local agent dynamics.

Optimality: Global optimal control of distributed systems is complicated by the fact that, for general LQR performance indices, the resulting optimal control is not distributed in form. Therefore, it cannot be implemented on a prescribed communication graph topology.  A condition is given for the existence of any optimal controllers that be implemented in distributed fashion.  This condition shows that for the existence of global  optimal controllers of distributed form, the performance index weighting matrices must be selected to depend on the graph structure.

Control Systems Chapter of Czechoslovak Section of IEEE together with Department of Control Engineering, FEE CTU in Prague invites anyone to a public talk given by Prof. Bassam Bamieh (University of California, Santa Barbara). The talks is organized thanks to the IEEE Control Systems Society Distinguished Lecturer Program (with partial suppport from the national chapter as well).
The talk will start at 14:30 and will last for about one hour. It will take place in the seminar room G205 on the second floor of G building in the Karlovo namesti campus of CTU in Prague.

Abstract of the talk: Networks of interconnected dynamical systems subject to stochastic disturbances exhibit scaling phenomena that are not present in deterministic networks. Standard notions of stability as a binary property (i.e. a system is either stable or not), or convergence rates, may fail to predict the behavior of large networks. This motivates the study of such networks using system norms as performance measures. This talk will specifically address the notion of network coherence under stochastic disturbances, and its dependence on network topology and various notions of network dimension. Regular lattices and fractal networks provide case studies with both integer and fractional dimension. We give asymptotic lower bounds on network disorder and show its dependence on both the complexity of individual node dynamics, as well as network dimension. It turns out that higher connectivity (network dimension) improves coherence, while more complex node dynamics can hinder it. However, in all cases there is a critical network dimension above which purely local interactions can lead to the emergence of global order. We outline the connections between these results and those on the statistical mechanics of harmonic solids, resistive lattices and random walks. We also present implications to the distributed control of vehicular formations and platoons, as well as phase synchronization in power networks with highly-distributed generation.

Bio: Bassam Bamieh is Professor of Mechanical Engineering at the University of California at Santa Barbara. He received his B.Sc. degree in Electrical Engineering and Physics from Valparaiso University (Valparaiso, IN) in 1983, and his M.Sc. and PhD degrees in Electrical and Computer Engineering from Rice University (Houston, TX) in 1986 and 1992 respectively. Prior to joining UCSB in 1998, he was an Assistant Professor in the Department of Electrical and Computer Engineering and the Coordinated Science Laboratory at the University of Illinois at Urbana-Champaign (1991-98). Professor Bamieh's research interests are in the fundamentals of Control and Dynamical Systems, as well as the applications of systems and feedback techniques in several physical and engineering systems. These areas include Robust and Optimal Control, distributed control and dynamical systems, shear flow transition and turbulence, and the use of feedback in thermoacoustic energy conversion devices. Professor Bamieh has co-authored over 100 refereed publications in Systems and Controls and allied fields. He has received several awards and honors for his research, including an IEEE Control Systems Society G. S. Axelby Outstanding Paper Award, an AACC Hugo Schuck Best Paper Award, and a National Science Foundation CAREER award. He was elected a Distinguished Lecturer of the IEEE Control Systems Society (2005), a Fellow of the International Federation of Automatic Control (IFAC) , and a Fellow of the IEEE with the citation "For contributions to robust, sampled-data and distributed control".

Prof. Bassam is staying in Prague Monday, March 18, through Wednesday, Monday 20 and is available for further scientific discussions.
