The area of adaptive systems, which encompasses recursive
identification, adaptive control, filtering, and signal processing,
has been one of the most active areas of the past decade. Since
adaptive controllers are fundamentally nonlinear controllers which
are applied to nominally linear, possibly stochastic and
time-varying systems, their theoretical analysis is usually very
difficult. Nevertheless, over the past decade much fundamental
progress has been made on some key questions concerning their
stability, convergence, performance, and robustness. Moreover,
adaptive controllers have been successfully employed in numerous
practical applications, and have even entered the marketplace.
This IMA Volume in Mathematics and its Applications DISCRETE EVENT
SYSTEMS, MANUFACTURING SYSTEMS AND COMMUNICATION NETWORKS is based
on the proceedings of a workshop that was an integral part of the
1992-93 IMA program on "Control Theory. " The study of discrete
event dynamical systems (DEDS) has become rapidly popular among
researchers in systems and control, in communication networks, in
manufacturing, and in distributed computing. This development has
created problems for re searchers and potential "consumers" of the
research. The first problem is the veritable Babel of languages,
formalisms, and approaches, which makes it very difficult to
determine the commonalities and distinctions among the competing
schools of approaches. The second, related, problem arises from the
different traditions, paradigms, values, and experience that
scholars bring to their study of DEDS, depending on whether they
come from control, com munication, computer science, or
mathematical logic. As a result, intellectual exchange among
scholars becomes compromised by unexplicated assumptions. The
purpose of the Workshop was to promote exchange among scholars
representing some of the major "schools" of thought in DEDS with
the hope that (1) greater clarity will be achieved thereby, and (2)
cross-fertilization will lead to more fruitful questions. We thank
P. R. Kumar and P. P. Varaiya for organizing the workshop and
editing the proceedings. We also take this opportunity to thank the
National Science Foundation and the Army Research Office, whose
financial support made the workshop possible. A vner Friedman

Since its origins in the 1940s, the subject of decision making
under uncertainty has grown into a diversified area with
application in several branches of engineering and in those areas
of the social sciences concerned with policy analysis and
prescription. These approaches required a computing capacity too
expensive for the time, until the ability to collect and process
huge quantities of data engendered an explosion of work in the
area. This book provides:* Succinct and rigorous treatment of the
foundations of stochastic control.* A unified approach to
filtering, estimation, prediction, and stochastic and adaptive
cools* The conceptual framework necessary to understand current
trends in stochastic control, data mining, machine learning, and
robotics.
Introducing the reader to the mathematics beyond complex networked
systems, these lecture notes investigate graph theory, graphical
models, and methods from statistical physics. Complex networked
systems play a fundamental role in our society, both in everyday
life and in scientific research, with applications ranging from
physics and biology to economics and finance. The book is
self-contained, and requires only an undergraduate mathematical
background.
The current state-of-art in securing computers and data is
tantamount to an arms race between the attackers on one hand and
the software developers who have to provide the updates to
counteract the attacks on the other. This monograph introduces a
novel technique for designing secure protocols with provable
security guarantees for wireless ad-hoc networks infiltrated with
adversarial nodes. It does this by developing a system-theoretical
approach to secure protocol design that provides provable and
comprehensive security guarantees, where any features of a protocol
that reduce complexity or maximize the network throughput do not
come at the expense of security. The desired approach is one of
security first and performance second, which is the reverse of the
current approach. This novel approach uses a game-theoretic
framework that addresses the deficiencies in the defense-in-depth
approach to securing complex systems. A Clean Slate Approach to
Secure Wireless Networking describes in detail the theory of using
this approach in both closed synchronized and unsynchronized
networks. It will be of interest to all researchers and designers
working on securing wireless networks.
This monograph presents a possible research agenda for analytics
and control of a deep decarbonized electric grid with pervasive
data, interactive consumers, and power electronics interfaces. It
focuses on new lines of investigation that are driven by new
technological, economical, and policy factors. Conventional
monitoring and control of the power grid heavily depends upon the
physical principles of the underlying engineering systems. There is
however increasing complexity of the physical models compounded by
a lack of precise knowledge of their parameters, as well as new
uncertainties arising from behavioral, economic, and environmental
aspects. On the other hand there is increasing availability of
sensory data in the engineering and economic operations and it
becomes attractive to leverage such data to model, monitor,
analyze, and potentially close control loops over data. The
increasing deployment of large numbers of Phasor Measurement Units
(PMUs) provides the potential for providing timely and actionable
information about the transmission system. Chapter 2 examines a
framework for drastically reducing the dimensionality of the high
volume streaming data, while preserving its salient features for
purposes such as event detection, classification and visualization,
and potentially even to close the loop around the data. Driven by
the deepening penetration of renewable energy resources at both
transmission and distribution levels, there is an increasing need
for utilizing power electronics interfaces as intelligent devices
to benefit the overall grid. Chapter 3 offers a conceptual design
and concrete examples of a qualitatively different power grid
stabilization mechanism in the context of networked microgrids.
Another major paradigm change in the operation of the grid is that
demand will have to be engaged much more to balance the partially
variable renewable energy supply, which in turn requires greater
understanding of human behavior to economic variables such as
price. Chapter 4 presents a possible formulation to model the
behavior of individual consumers in future grid operations. Chapter
5 presents a proposed solution to the problem of detecting attacks
on the sensor measurements in the grid, which has become a greater
concern with increasing reliance on sensor data transported over
communication networks, with both sensors and networks liable to
malicious cyber-attacks. The goal of this monograph is to design
clean, affordable, reliable, secure, and efficient electricity
services. and to expand the horizon of the state of the research in
the electric energy systems, at a critical time that is seeing the
emergence of Grid 3.0. It is by no means complete and aims to
stimulate research by next generation researchers.
