Title of the paper: Ostensible Positive Dynamical Linear Uncertain Systems: Properly Set Goals, LMI Synthesis, Constraints and Quadratic Stability
Abstract: In this talk, a review of recent studies on ostensible positive uncertain dynamical systems is
presented, focusing on some foundational results for control design condition settings, reflecting
composed system state matrix representation, diagonal stabilization principle, non-negative parametric
constraints, and quadratic stability. A view of the above topic for a class of uncertain ostensible positive
systems, with the specific objective of the roles the element-wise non-negative parameter bounds will be
presented, to illustrate how to solve the interval observer design problem for given complexity of the
interval matrix parameter structures. Finally, some specific examples will show the interest of the results
in suitable application domains, with discussion of future challenges.
Bio:
Dušan Krokavec received his M.Sc. degree in automatic control and his Ph.D. degree in technical
cybernetics from Slovak University of Technology in Bratislava, Slovakia in 1967 and 1982, respectively.
After stint at VUMA research institute (Nové Mesto n/Váhom, Slovakia) he joined the Technical University
of Košice (TUKE, FEI), Slovakia in 1971, receiving a full professorial title in automation and control in 1999.
Remained on the faculty there until his retirement at the end of 2015, he was designated an emeritus
faculty at this point. He has been studying control theory for complex system design and its
transdisciplinary applications in science and technology from the viewpoint of dynamic system fault
diagnosis and fault tolerant control. His main research interests are in stochastic processes, Kalman
filtering and stochastic teams, fault detection of dynamic systems using models and data-driven
approaches, synthesis of control over networks, as well as multi-agent system control. He is a pioneer in
the field of methods of analysis and synthesis of linear positive systems with Metzler dynamics, based on
linear matrix inequalities. He authored or co-authored more than 200 research papers in archival journals,
book chapters, and international conference proceedings.
Prof. Krokavec is the members of the IFAC Technical Committee TC 1.4 Stochastic Systems and the IFAC
Technical Committee TC 6.4 Fault Detection, Supervision & Safety of Technical Processes - SAFEPROCESS.
