Title: "Dynamics of parametric and self-excited systems: analysis and applications"

  • Organizers: Fadi Dohnal (UMIT, Austria) and Jerzy Warmiński (Lublin University of Technology, Poland)
  • Self-excited or parametrically excited vibrations are well known and deeply studied in the literature. However, such system are again under focus, especially in the context of modern MEMS, energy harvesters or macroscopic systems like helicopter blades or other flexible structures like rotors. Self-excited vibrations are observed during brake squeal, galloping vibrations of overhead transmission lines, or at critical operation of fluid-film bearings. These vibrations are in general unwanted but need careful modelling and analysis for a system design that avoids self-excited vibrations. Parametrically excited vibrations are increasingly introduced on purpose in modern vibration systems in order to enhance or tune its performance, sensitivity, etc. An exciting area of research is the interaction between self-excited and parametrically excited systems which may lead to phenomena like (non-)linear interactions. New numerical and advanced analytical tools help in gaining new understanding of the dynamics of such systems that is a key for potential implementation in real products. The motivation is to demonstrate new dynamic phenomena, which arise during interaction of different vibration types, demonstrate technique to design and control such structures by e.g. time delay control or other control strategies. The special thematic session is dedicated to theoretical works and as well as to practical examples of such structures.

Title: "Analysis and control of bioinspired and biomimetic dynamical systems – sensors, manipulators and locomotors"

  • Organizers: Carsten Behn (Schmalkalden University of Applied Sciences, Germany) and Ambrus Miklós Zelei (Budapest University of Technology and Economics, Hungary)
  • Bioinspired and biomimicking design concepts are in special focus of researchers and engineers, since nature is a good source of great design concepts and ideas. Biomimetic and bioinspired systems for any kind of locomotion (e.g., flying, crawling, rolling, digging) as well as for tactile sensing in robotics (e.g., monitoring devices, devices for environment detection and recognition, path planning) are the subject of daily research worldwide.

    This Special Session collects several highlights from the state-of-the-art results on the dynamic analysis and control of these bioinspired and biomimetic systems.

    Autonomous mobile systems play a very important role, since they can move independently in space. Our session does not only focus on limbless and legged terrestial locomotion, but also on flying and underwater locomotion. At this point, compliant actuators and artificial muscles with adjustable stiffness come into the picture. The challenge here is the control of these typically underactuated systems. Such state-of-the-art control algorithms are frequently used in exoskeletons and human motion assistance systems, too.

    The nature provides a wide range of ideas which are used in robotic sensing, such us vibrissae and tactile sensors. The research on the analysis of biological sensors and the design of technical sensor systems based on these results (bio-inspired sensors) are currently being established worldwide. Through the combination of different viewing and (in the mechanical sense) model levels, the structure and operation of sensor systems are examined and the transfer of the determined functional principle into the technology is made. Based on mechanical models, the perceptual capabilities of the biological organs are adaptively mapped and analyzed.

    Natural structures, such as the human body, typically possess high redundancy both on kinematic and on dynamic level (we can think about the reaching movement of the human arm). The redundancy resolution and optimization algorithms of the engineering systems are inspired by the biological examples in many cases.

    Our Special Session highly welcomes contributions from these kinds of research fields. In all the above listed research fields, the experimental analysis, the modelling and the model based dynamic analysis of the natural phenomena fit into our Special Session, as well as the control design of biomimetic and bioinspired systems, including global optimization and redundancy resolution.

Title: "Mathematical modeling of nonlinear systems involving interaction with the medium"

  • Organizers: Marat Dosaev (Lomonosov Moscow State University, Russia and National Taiwan University of Science and Technology, Taiwan) and Yury Selyutskiy (Lomonosov Moscow State University, Russia)
  • Interaction between rigid bodies and different types of media takes place in many problems applications pertaining to different areas of engineering. Mathematical simulation of effects (which are often highly nonlinear) resulting from such interaction is of both fundamental and application interest. The session will consider different problems in nonlinear dynamics of such systems, including dry friction and viscoelastic support effects in problems of contact between bodies, interaction between flow and bodies, mechanical behavior of molded composite material interacting with rigid walls, and so on.

    Construction of mathematical models and study of specific features of such dynamic systems is crucial for efficient design and control of the corresponding technical objects. Special attention will be paid to construction and analysis of closed semi-empirical dynamic models containing a small number of parameters. Questions of parametric optimization, bifurcations, damping or excitation of oscillations, control, stabilization of program motions and equilibria will be discussed.

Title: "MegaCities: Nonlinear dynamics and networks"

  • Organizer: Gerard Olivar (UNAL, Colombia)
  • In 2015, the United Nations approved the 2030 agenda on Sustainable Development, considering the need for cities and human settlements to be inclusive, safe, resilient and sustainable. Urbanization and the growth of cities result in the concentration of the population and the growing demands for infrastructure and basic services to improve the quality of life and the competitiveness of cities.

    Construction of mathematical models and study of specific features of such dynamic systems is crucial for efficient design and control of the corresponding technical objects. Special attention will be paid to construction and analysis of closed semi-empirical dynamic models containing a small number of parameters. Questions of parametric optimization, bifurcations, damping or excitation of oscillations, control, stabilization of program motions and equilibria will be discussed.

    Statistics for 2015 show that close to 4,000 million people (54% of the world population) lived in cities, and according to projections in 2030, 60% of the world population will live in urban areas, which will be distributed in almost 82% of the population in developed countries and 56% of the population in developing countries. On the other hand, and due to the expansion of urbanization, the absolute number of people living in rural areas will not change significantly. Highly urbanized countries tend to have high levels of human development. Urban areas currently generate around 80% of the world's gross domestic product. Resource-efficient cities can combine increases in productivity and innovation with reduced environmental impacts, generating greater economic output with much lower greenhouse gas emissions and lower consumption per person of resources. Dense urban mixed-use settlements can be more efficient in the use of resources than any other with similar levels of economic production. On the contrary, densely planned and deficient urban settlements generate congestion, overcrowding, pressure on infrastructure and the environment, and higher housing costs.

    However, the most worrying effects of urbanization are:

    • Inequality, since there are 828 million people poorly living and this figure continues to rise
    • The levels of energy consumption and pollution in urban areas. Although cities occupy only 3% of the land surface, represent between 60% and 80% of energy consumption and 75% of carbon emissions are attributed to around half of anthropogenic carbon dioxide emissions and environmental / ecosystem degradation

    The session will focus on nonlinear, and sometimes nonsmooth, models describing the dynamics of urban metabolism, mobility, and health issues.

Title: "Synchronization and nonlinear normal modes in physics and structural dynamics"

  • Organizers: Margarita Kovaleva, Leonid Manevitch (Moscow Institute of Chemical Physics, Russian Academy of Sciences, Russia) and Valery Pilipchuk (Wayne State University, Michigan, USA)
  • As wide interdisciplinary areas, synchronization and nonlinear normal modes (NNMs) appear to deal with the same type of physical phenomena using nevertheless different mathematical formalisms describing phase states of oscillatory arrays and structural mode shapes, respectively. Very recently however a new type of nonstationary synchronization was revealed that bridges the gap between the modal and phase visualizations. Therefore, we hope that bringing together young and experienced scientists from both areas will facilitate the interexchange of new ideas and understanding of different analytical, numerical, and experimental tools at this cutting edge of nonlinear sciences and the related practical applications.

    Tentative topics:

    • Nonlinear normal and local modes in structural dynamics
    • Amplitude modulations and phase oscillators
    • Amplitude modulations and phase oscillators
    • Synchronization in complex systems
    • Self‐sustained oscillations of oscillatory arrays

Title: "Dynamics of vehicles"

  • Organizers: Andrzej Harlecki (University of Bielsko-Biala, Poland)
  • Papers presented within the special session will deal with an analysis of the dynamics of motor vehicles, including cars and trucks, their trailers, and motorcycles. Advanced mathematical formalisms, such as the method based on the homogeneous transformations, will be discussed. Selected issues concerning the dynamics of motor vehicles, including problems related to their maneuverability and vibrations of their elements, will be analyzed. The abovementioned topics have great practical significance also for the development of the automotive industry. It is also worth mentioning that the issues connected with the dynamics of motor vehicles were already analyzed during previous editions of DSTA, but they have never been dealt together within one session.

Title: "Advances in fractional order modelling and control"

  • Organizers: Cristina Muresan (Technical University of Cluj-Napoca, Romania), Carla Pinto (Instituto Superior de Engenharia do Porto) and Eva Dulf (Technical University of Cluj-Napoca, Romania)
  • Fractional order differentiation is a generalization of classical integer differentiation to real or complex orders. In the last couple of decades, the use of fractional order calculus in modelling and control applications has seen a tremendous increase in research papers. This is mainly due to arguments recommending fractional calculus as an optimal tool to describe the dynamics of complex systems and to enhance the performance and robustness of control systems. Among these, fractional order PID controllers tuning, implementation and experimental validation occupy an important place.

    However, there are still many issues and open problems that need to be addressed in this area. This special session welcomes papers dealing with fractional calculus in modelling and control applications and aims at presenting some recent developments in this area of research. We welcome any contribution within the general scope of the Special Session theme "Advances in Fractional Order Modelling and Control".
