In Pragueon November 15, 2022 
Dear Conference Organizers, Technical Sponsors, Travel agencies, Airlines, Proceedings publishers and Participants:
The local organizing team has made the difficult choice to hold the conference entirely online in June 2023 after great discussion and consideration.
The regional organizing committee has been keeping a careful eye on the issue. Since a further significant increase in energy and maintenance costs is anticipated in January 2023 (hence the decision to delay the start of the spring semester until the end of January), it is impossible to estimate the costs associated with holding the conference. Even now, electricity costs in the Czech Republic increased by 62% in a month (see on-saving-energy-amid-highest-electricity-price-increase-in-eu). Several variables, including the weather, whether electricity must be supplied from the EU to Ukraine, and whether a new wave of Ukrainian refugees will arrive in Czechia during the winter, will affect the anticipated future price hike. As a result, if conference prices are set at this time, they might not be enough to pay the true costs of holding the conference in June 2023. Additionally, the cost of flight tickets is rising steadily, and there aren't many participants who can enter the Czech Republic without a visa.
We have come to the conclusion that it is not advisable to hold this conference in person at this time in June 2023. However, as the conference has already been postponed once due to the COVID pandemics, we don't want to do it again. As a result, we had to make the painful choice to hold the conference entirely online in June 2023.This is not a decision we have taken lightly, and we regret having to postpone an occasion that will foster tremendous collaboration value and provide a springboard for future endeavors. Our top objective, however, is to proactively take all safety and health precautions for the benefit of everyone present and the general public. In addition to this, an increasing number of presenters are now subject to travel limitations, which makes it harder for us to deliver the high-quality in-person experience for which this conference has become recognized over the past 25 years. The following conference will take place in person.
The registration costs and other cost-related issues will be updated in January 2023, while the conference website will be updated very shortly. Update your submissions, please.
The organizing committee chairs, session organizers, keynote speakers, organizing committees, technical sponsors, and all other attendees are especially appreciated for their perseverance in adjusting to the difficult decision to have the conference completely online in June 27–30, 2023. We appreciate your flexibility as we work together to address this unprecedented situation.
Thank you for your continued support.

SS 2: The Navier-Stokes equations and the phenomenon of turbulence

Abstract: Waves follow our boat as we meander across the lake, and turbulent air currents follow our flight in a modern jet. Mathematicians and physicists believe that an explanation for and the prediction of both the breeze and the turbulence can be found through an understanding of solutions to the Navier-Stokes equations. Although these equations were written down in the 19th Century, our understanding of them remains minimal. The challenge is to make substantial progress toward a mathematical theory, which will unlock the secrets hidden in the Navier-Stokes equations.

SS3: Inductive levitation micro-systems for applications in sensors and actuators: recent development, challenges, and outlook

Abstract: Electromagnetic levitation, through remote forces, eliminates completely mechanical contact and wear, a need for fluid- or gas-bearing in moving parts of micro-systems. Consequently, it is a fascinating means to overcoming the domination of friction over inertial forces at the micro-scale. In particular, recent development in 3D micro-coil technology has announced inductive levitation micro-systems (ILMS) as a promising technology for creating a new generation of micro-sensors and –actuators with higher performance. The established micro-fabrication process, passive and simple – these are the attractive qualities of ILMS. In this talk, we will discuss new challenges facing ILMS in terms of technology and modeling. Also, new critical applications of ILMS in solid-state NMR, inertial sensors based on dynamic tuning and smart micro-actuation systems will be introduced.

SS5: Analysis and Applications of Fractional Differential and Difference Equations

Abstract:: Study of fractional differential equations and difference equations are emerging as a powerful tool for modeling complex dynamical systems. It has been demonstrated that fractional differential equations and difference equations represent better and more economical models than their counterpart of integer derivative models.  Modeling via fractional differential or difference equations has been established as a better representative model in various fields of mechanics, electricity, chemistry, biology, medicine, economics, control theory, as well as signal and image processing.  The main advantage of fractional dynamic systems over the integer derivative model   is that the effect is global in nature rather than local. That is mainly because the integer derivative is local whereas the fractional derivative is global in nature.

SS11:  The perturbation methods and the applications and High Performance Computing

Abstracts : The new versions of information models and specialized computing machines with an open architecture, as well as methods for their use in the field of computational informatics, together providing an addition to the algorithmic base High performance computing.

An essential technical feature of CIT, which largely determines its operational qualities, is the use of specialized computing machines (VMs) with an open architecture, which, together with the developed information models, provide High Performance Computing.

It seems important to note the system-forming role of specialized computers, as well as the ability to extract completely new information about the information connections between individual (elementary) operations, in terms of which the process as a whole is described.

The central role of CIT in these structures is to apply information and knowledge to the generation of new knowledge, leading to a radical change in the methodological foundations of the formation and use of all the basic elements of Numerical methods, defining a new way of thinking in Applied and Fundamental Mathematics.

SS13: Special Session: Fractional wavelet joint analysis with applications

Abstract: This session is dedicated to recent results of the fractional wavelet joint analysis and their applications both to other fields of Mathematics and to other applied sciences. This joint analysis provides several tools for solving differential, integral, integro-differential equations and modeling in mathematical physics. In particular, both image processing and electromagnetism have shown that the fractional-wavelet approach can shed some new light on several unsolved problems. In fact, nonlinear models are often described and approximated by fractional models and wavelet expansions, respectively. Both theories show rather strikingly that contemporary mathematics is capable of providing ever more refined models for real-world applications. In addition to this, the fractional calculus of complex functions has merited increasing consideration from the international mathematics community, thus making the fractional calculus of special functions one of the most interesting research topics in contemporary mathematics.

SS 15 Metric Geometry and Variational Problems

Abstract: In this session we are going do discuss classical and modern results in metric geometry theory. In particular, we are interested in geometry of hyperspaces endowed with Hausdorff or Gromov-Hausdorff distance function, and the geometry of Gromov metric triples, i.e., Polish metric spaces endowed with Borel measures. Another subject is devoted to geometry of extremals of variational problems, in particular, of geodesics, minimal networks (branched geodesics), minimal surfaces (multidimensional version), and Gromov minimal fillings. The mixture of the previous subjects leads, for instance, to classical Steiner problem in Gromov-Hausdorff space, or to transportation problems in the sense of Kantorovich, Rubinstein, Wasserstein, etc. All specialists interested in the subjects mentioned above and any related aspects are welcome to join the session.

One day Workshop on

Simple Adaptive Control
New Results Simplify Stability Analysis

Organizer and Speaker

Itzhak Barkana – BARKANA Consulting


Simple Adaptive Control (SAC) techniques have been conceived for large-scale systems. While initially considered to be just a modest version of the standard Model Reference Adaptive Control (MRAC), it was only before appropriate mathematical tools of analysis had been developed. Further developments showed that they can easily be applied to such applications as robots, planes, missiles, satellites, fine motion control, etc. Various drawbacks related to classical MRAC have been addressed and eliminated and conditions needed for robust stability have been significantly mitigated. Recent developments in nonlinear systems stability analysis tools lead to clear proofs of SAC stability in realistic environments. Realistic examples from various domains of flight control, guidance and aerospace are used to show that indeed SAC is the Stable Direct MRAC methodology. A non-minimum-phase and unstable UAV will be used as a detailed case-study to show the simplicity of SAC as an Add-On to classical control design which improves performance. Application to real hardware will be demonstrated.

About the general topic of nonlinear systems stability analysis, although Lyapunov stability theory is the customary basis of any modern stability analysis, its direct application requires fitting a Positive Definite function to the system whose derivative ”along all trajectories of the system” is Negative Definite, whereas in most non-trivial problems the derivative is at most Negative Semi-Definite. Because early extensions of Lyapunov stability theory were only covering autonomous systems, various alternatives were sought for nonautonomous systems. An alternative provided by Barbalat Lemma imposes conditions of uniform continuity of functions and even continuity of derivatives that again could limit its applicability. Besides, even when applicable, it only ends with partial results. Although extensions of LaSalle's Invariance Principle to nonautonomous systems have been available at least since 1976, they have remained surprisingly unknown for large circles of the nonlinear control community. Also, even if assumable known, misinterpretations of its larger mathematical scope (that covers much more than mere asymptotic stability) may have misled the users with respect to its usefulness. Moreover, in the light of LaSalle's observation and emphasized by Matrosov school of stability, a review of present stability results seems to show that the net result of analysis in the negative semidefinite case is not more than simple stability, which was already there in Lyapunov original Theorem. Apparently, one would have to find and use a combination of multiple Lyapunov functions in order to get more relevant results. Instead, revisiting the various alternatives to stability analysis and new results based on LaSalle’s Invariance Principle may help showing the extreme efficiency of the new Theorems of Stability to nonlinear systems stability analysis.

Keywords: Control, Adaptive Control, Positive Realness and Passivity, Lyapunov methods, Barbalat’s Lemma, LaSalle’s Invariance Principle, New Theorem of Stability


I)       The need for adaptation

  • Life is with uncertainty: need various gains for various situations - change in nominal parameters or various operational conditions
  • Non-stationary gains: the right gains at right times. Good idea, yet… must be careful.
  • Example: The danger of “safe” fixed control in nonstationary environments

II)    Review of other Adaptive Control approaches.

  • First Adaptive Control ideas: ingenious yet ended in failure
  • Basic MRAC: First rigorous stability proofs, problematic SPR conditions
  • “Classical”  MRAC: Stability in ideal situations, problems otherwise:

- Unmodeled dynamics

- Persistent excitation

- Bursting, etc.

III) Simple Adaptive Control for Engineers

  • Presentation of the Simple Adaptive Control (SAC)

- Conditions for SAC implementation in Engineering terms

- The Add-On SAC: rational and architecture.

- Advantages of the Add-On SAC - robust stability and performance  are independent

- Examples

IV) Optimal Control based architectures

- Short review of Optimal Control and Tracking

- Optimal Control as architecture generator

- The role of feedforward for good/perfect tracking

- Sensitivity to feedforward parameters motivates the need for adaptation

- Can Adaptive Control use and extend ideas from Optimization to the world of uncertainty?

V)    The role of passivity in Adaptive (or any Nonlinear) Control

- Stability conditions in Engineering terms

- Relation between Stability and Passivity

- Passivity and Almost Passivity in Engineering terms


VI) New stability results and their implications to SAC.

  • Lyapunov’s approach to stability (around 1900)
  • First extensions: Barbashin-Krasovskii and LaSalle, The Invariance Principle for Autonomous systems only (1950-1960)
  • Second extension for Non-autonomous systems: Barbalat’s Lemma (around 1970): the apparent need for uniform continuity (or the implied “threat” of discontinuity).
  • Further extensions: (The real and ignored) LaSalle’s Invariance Principle for Non-autonomous systems (1976-1980)
  • The new Theorems of Stability (2013-2016): simple and safe tools for proofs of stability
  • Example problems

VII)                      Application of the SAC algorithm

  • Unstable MRAC “counterexamples” become simple examples for SAC
  • Explicit design case: Combining Classical LTI design and SAC guarantee stability and lead to superior performance for Non-minimum Phase UAV.
  • Missile
  • Flexible structures: new developments relax the need for collocation
    • Example Problems
  • Application of the Add-On SAC algorithm to real SISO and MIMO Hardware
  • Advanced issues (time permitting): gain convergence, participants proposed examples
