Special Sessions & Interactive Sessions & High School Event

SPECIAL SESSIONS

Special Session I: Wednesday: 11:30AM – 1:10PM, Grand Ballroom I
Scanning Probe Microscopy
Organizer: Murti V. Salapaka. Iowa State University
Scanning probe microscopy has revolutionized science and engineering in the past decade. As
stated in the National Nanotechnology Initiative plan “These instruments including the
scanning tunneling microscopes, atomic force microscopes and near-filed microscopes,
provide the eyes and fingers for nanostructure measurement and manipulation”. There are
significant advancements that have to be unraveled in this area where the control expertise can
play a pivotal role. In this session the contribution of the control and systems perspectives to
this area will be highlighted, and open research issues will be presented. Presenters will
include Murti V. Salapaka (Iowa State University), Srinivasa Salapaka (University of Illinois,
Urbana Champaign) Anil Gannepalli (Asylum Research), and Abu Sebastian (IBM, Zurich
Labs.).

Special Session II: Wednesday: 11:30-1:10PM, Grand Ballroom II
Modeling of RNA Expressions
Organizer: Bijoy Ghosh, Washington University
An important area of Systems Biology concerns the problem of controlling photosynthesis by
environmental alterations. One is interested in the study of how `Genes Regulate’ and one
way to do this is to classify a set of co-regulated genes. There are many different criterion in
the literature on how to assess that a set of genes are co-regulated, and a well known technique
utilizes ‘Pearson Correlation Coefficient’. Thus two genes are described as co-regulated, if
their expressions over time are close. This session will focus on the construction of ‘Dynamic
Interaction Model’ between co-regulated genes to study the effect of ‘temporal causality’
between interacting genes. The proposed model is linear, time-varying and captures the
temporal interaction between gene clusters. The model is time varying, indicative of the fact
that the interaction profile can change over the life cycle of the cell. Our model would utilize
recently developed techniques in ‘Smoothing Splines’ and time series analysis methods that
have been shown to be useful in spaces of large dimension such as ‘Random Matrix Theory’
and ‘Sparse Principal Component Analysis.’ We believe that the model so developed would
find application in the study of the control of photosynthesis.

Special Session III: Wednesday: 6:00-7:30PM, Grand Ballroom I
History of Control
Background Information
Organizer: Daniel Abramovitch, Agilent Labs

Mid-Career Professional: To Change or Not Change Your Jobs
Organizer: Karlene Hoo and F. Chowdhury, Texas Tech University
This session provides a forum for discussing important aspects of job direction change for the
mid-career professional. To make a change or to not make a change? What are the important
factors to be considered? There will be presentations from successful mid-career professionals who
changed jobs and moved to other positions, and there will be a question/answer period with
audience participation.

Special Session V: Friday: 11:30-1:00PM, Grand Ballroom I
NSF Funding Opportunities
Organizers: Kishan Baheti and Mario Rotea, National Science Foundation.
National Science Foundation continues to be the funding source of choice for control systems
engineers. However, programs at the NSF are being reorganized continually, and along with

Practical Techniques in Control Engineering (2 days: June 6 & 7, 2005)
Dennis S. Bernstein, University of Michigan and Carl R. Knospe, University of Virginia
Course Description (short version) See longer PDF Description
Provides a bridge between recent developments in control theory and their practical application in the laboratory and industry. Fundamental tradeoffs, modeling and identification, linear and nonlinear controller synthesis, saturation, and adaptive tuning will be discussed. The course is suitable for students, instructors, and researchers in control theory who wish to obtain a broad perspective of the control engineering enterprise as well as control engineers from all industrial applications seeking a coherent, self-contained overview of recent developments relevant to control practice.

Engineering Applications in Genomics (2 days; June 6 & 7, 2005)
Aniruddha Datta, Texas A & M University
Course Description (short version)
Genomics concerns the study of large sets of genes with the goal of understanding collective function, rather than that of individual genes. Such a study is important since cellular control and its failure in disease result from multivariate activity among cohorts of genes. Very recent research indicates that engineering approaches for prediction, signal processing and control are quite well suited for studying this kind of multivariate interaction. The aim of this workshop will be to provide the attendees with a state of the art account of the research that has been accomplished in this field thus far and
to make them aware of some of the open research challenges.

Recent Advances in Subspace System Identification: Linear, Nonlinear, Closed-Loop, and Optimal with Applications (2 days; June 6 & 7, 2005)
Wallace E. Larimore, Adaptics, Inc.
Course Description (short version) See longer PDF Description
This workshop presents a first principles development of subspace system identification (ID) for linear, nonlinear, and closed-loop systems using the maximum likelihood method. This gives optimal parameter estimates and likelihood ratio tests of hypotheses on model order/structure and tight Cramer-Rao accuracy bounds. These new results along with the superior computational properties of subspace ID greatly extend the potential applications. Examples discussed include closed-loop linear and nonlinear systems for monitoring, fault detection, control design, and robust and adaptive control. No prior knowledge of the subject is assumed.

Real Time Optimization By Extremum Seeking Control (1 day; June 7, 2005)
Miroslav Krstic, University of California, San Diego
Kartik Ariyur, Honeywell Aerospace Electronic Systems
Andrzej Banaszuk, United Technologies Research Center
Dobrivoje Popovic, United Technologies Research Center
Eugenio Schuster, Lehigh University
Mario Rotea, Purdue University
Course Description (short version)
Extremum seeking control, a popular tool in control applications in the 1940-50's, has
seen a resurgence in popularity as a real time optimization tool in aerospace and automotive engineering. Extremum seeking is a non-model based method of adaptive control, and, as such, it solves, in a rigorous and practical way, some of the same problems as intelligent control techniques. This workshop will present the theoretical foundations and selected applications of extremum seeking. The first half of the workshop will teach the attendees the extremum seeking algorithms, the basics of their stability analysis, and the design guidelines. Both single-parameter and multivariable problems will be covered, as well as both the continuous and discrete time implementations. A novel "slope seeking" extension applicable to some unstable plants will be introduced. An application of extremum seeking to minimizing limit cycles caused by actuator limitation will be presented. In the second half of the workshop, applications to aerospace and propulsion problems (formation flight, combustion instabilities, flow control, compressor rotating stall), automotive problems (anti-lock braking, engine mapping), and bioreactors, will be presented.
