Bode Lecture Title:
High-gain Observers in Nonlinear Feedback Control
Friday, 11:00-12:00pm, Large Hall
Abstract:
High-gain observers play an important role in the design of feedback control for nonlinear systems. This lectures overviews the essentials of this technique. After a brief historical background, a motivating example is used to illustrate the main features of high-gain observers, with emphasis on the peaking phenomenon and the role of control saturation in dealing with it. The use of the observer in feedback control is discussed and a nonlinear separation principle is presented. The use of an extended high-gain observer as a disturbance estimator is covered. Challenges in implementing high-gain observers are discussed, with the effect of measurement noise as the most serious one. Techniques to cope with measurement noise are presented. The lecture ends by listing the speaker's experience with experimental testing of high-gain observers.

Plenary Title:
Fragility of Networked Systems
Tuesday, 8:30-9:30am, Large Hall
Abstract:
The emergence of large networked systems has brought about new challenges to researchers and practitioners alike. While such systems perform well under normal operations, they can exhibit fragility in response to certain disruptions that may lead to catastrophic cascades of failures. This phenomenon, referred to as systemic risk, emphasizes the role of the system interconnection in causing such, possibly rare, events. The flash crash of 2010, the financial crisis of 2008, the New England power outage of 2003, or simply extensive delays in air travel, are just a few of many examples of fragility and systemic risk present in complex interconnected systems.
Robust interconnections have been the subject of study by the control community for several decades. Substantial progress has been made in the context of both stability and performance robustness for various types of interconnections. Typical problems addressed in the literature involve interconnections with simple topologies, but with more complex components (dynamic, sometimes with high dimensions).
More recently, the attention of the research community has shifted towards networked systems where the topology of the network is fairly large and complicated, while the local dynamics are fairly simple. The term fragility is used in this context to highlight the system's closeness to failure. Notions of failure include large amplification of local disturbances (or shocks), instability, or a substantial increase in the probability of extreme events. Cascaded failures, or systemic risk, fit under this umbrella and focus on local failures synchronizing to cause a breakdown in the network. Many abstracted models from transportation, finance, or the power grid fit this framework well. The focus of research is to relate fragility to the size and characteristics of a network for certain types of local interactions.
In this talk, I will address this emerging area. I will provide some constructive examples and highlight important research directions.

Cambridge, MA, where he is now the William A. Coolidge Professor of EECS. He is currently the acting director of the Engineering Systems Division, and Director-designate of a new organization addressing major societal problems through unification of the intellectual pillars in Statistics, Information and Decision Systems, and Human and Institution Behavior. Previously, he held the position of Associate Department Head of EECS. He has been a visiting Professor at the Department of
Electrical Engineering, California Institute of
Technology, Pasadena, CA, for the Spring of 1993. He has consulted for various national research laboratories and companies.
Dr. Dahleh is interested in Networked Systems with applications to Social and Economic Networks,
Transportation Networks, and the Power Grid. Specifically, he focuses on the development of foundational
theory necessary to understand, monitor, and control systemic risk in interconnected systems.
His work draws from various fields including game theory, optimal control, distributed optimization,
information theory, and distributed learning. His collaborations include faculty from all five schools at MIT.
Dr. Dahleh is the co-author (with Ignacio Diaz-Bobillo) of the
book Control of Uncertain Systems: A Linear Programming Approach,
published by Prentice-Hall, and the co-author (with Nicola Elia)
of the book Computational Methods for Controller Design published by
Springer. He is the three times recipient of the George Axelby outstanding
paper award for best paper in IEEE Transactions on automatic control. He is also
the recipient of the Donald P. Eckman award
from the American Control Council in 1993 for the best control engineer under 35.
He has given many keynote lectures at major conferences.

Plenary Title:
Network Systems in Science and Technology
Wednesday, 8:30-9:30am, Large Hall
Abstract:
Network systems are mathematical models for the study of cooperation,
propagation, synchronization and other dynamical phenomena that arise among
interconnected agents. Network systems are widespread in science as they
are fundamental modeling tools, e.g., in sociology, ecology, and
epidemiology. They also play a key growing role in technology, e.g., in the
design of power grids, cooperative robotic behaviors and distributed
computing algorithms. Their study pervades applied mathematics.
This talk will review established and emerging frameworks for modeling,
analysis and design of network systems. I will survey the available
comprehensive theory for linear network systems and then highlight selected
nonlinear concepts. Next, I will focus on recent developments by my group
on (i) modeling of the evolution of opinions and social power in social
networks, (ii) analysis of security and transmission capacity in power
grids, and (iii) design of optimal strategies for robotic routing and
coordination.

Plenary Title:
Distributed Energy Management Systems toward Smart Cities: International Research Collaboration
Thursday, 8:30-9:30am, Large Hall
Abstract:
In the interim report on the fifth Science and Technology Basic Plan of Japan, the realization of Super Smart Society in our future is highlighted. The initiative for Smart Cities has been also promoted worldwide as societal-scale CPS (Cyber-Physical Systems) infrastructures. Along with efficient traffic/water/security management, distributed EMS (Energy Management Systems) should play a key role as we head toward low carbon environmental friendly society that is essential for sustainable development. To this goal, JST (Japan Science and Technology Agency) has launched a CREST research area for the distributed EMS building. The aim of this project is to create fundamental theory and advanced technology for optimal control of energy balancing between dynamic demand and supply. The topics covered include forecast and integration of renewable energy, management of electric vehicle/storage, demand response and human behavior, development of demand model, and platform building. A particular emphasis is on the promotion of international research collaboration with the US and European Funding Agencies, such as NSF (USA), DFG (Germany), RCN (Norway), CNR (Italy) and others. This would enable all the project researchers involved to catalyze networking and knowledge sharing with a broad array of disciplines. In this talk, the on-going exciting progress of the CREST EMS project will be presented.
