V rámci vedeckých seminárov "Research Seminars on Smart Cybernetics" projektu FrontSeat financovaného Európskou úniou si v stredu 8.2.2023 vypočujeme prednášku na tému "Soft Sensors: Applications and Rumination". Prednášku bude viesť Prof. Yuri Shardt, ktorý pôsobí ako profesor na oddelení automatizácie, Technical University of Ilmenau, Nemecko.
Bio: Prof. Dr. Yuri A.W. Shardt is the chair of the Department of
Automation Engineering at the Technical University of Ilmenau, Germany,
working on the development of advanced system identification and fault
detection and isolation methods for application to industrial problems.
He teaches courses in automation engineering, statistics, and system
identification. He has worked at the University of Waterloo, the
University of Duisburg-Essen as an Alexander von Humboldt Fellow, in the
ceramics and glass-making industry, and at the University of Alberta.
In these jobs, his research focused on the development and
implementation of advanced control methods for complex and uncertain
systems. He has written over 50 journal papers and a book called
Statistics for Chemical and Process Engineers: A Modern Approach (now in
its second edition), which has also been translated into German. He has
also presented numerous conference papers. He is also an associate
editor for the journal ISA Transactions.
Abstract: As the world
becomes increasingly interconnected and tightly controlled, the need to
measure each and every variable becomes increasingly important.
Unfortunately, not every variable can be measured accurately in real
time, for example, concentrations of complex, multiphase mixtures or the
chemical properties of films may be extremely difficult to measure
accurately in real time as quickly as necessary for process monitoring
and control purposes. One common solution is the use of soft sensors
that take the available process information and provide a forecast or
prediction of the difficult-to-measure variables. Soft sensors are
essentially a mathematical model relating the easy-to-measure variables
with the difficult-to-measure variables. These models are developed
using methods ranging from simple regression analysis to the most
complex machine learning and artificial intelligence. However, not only
must the models be accurate, but the configuration of the soft-sensor
system within the overall process must be considered. An improper
configuration can lead to poor overall soft-sensor forecasts. Additional
concerns include updating the models as the underlying process changes
over time. Such methods such as adaptive learning, just-in-time
modelling, or re-identification can be considered. This presentation
will focus on providing an overview of soft sensors, their application,
and future directions.
