text: Verification planning for engineering complex systems lacks a systematic procedure
for creating test scenarios. Test scenarios can be generated by combining test
cases, or by integrating test cases into pre-specified scenarios. Based on a systematic
literature analysis a method is developed to simplify verification planning by
creating new test scenarios and enriching existing ones. To assist the V&V engineer
in planning test scenarios, a catalogue of combination premises is created to
support the method. The method is evaluated in the development of a platform for
emergency management. Evaluation proves that the method makes modelling of test
scenarios more efficient.

text: The increasing complexity of technical systems requires early, structured
verification and validation (V&V). Existing metadata models only map parts of
the engineering process and do not enable a continuous chain of effects from requirements
to test results. The aim of this publication is to develop a holistic V&V metadata
model for the consistent, transparent and machine-processable description and
linking of relevant engineering artifacts. In a five-stage research approach,
essential model components are derived from literature and are integrated into
a holistic model. Initial applications as part of a European research project
show the potential of the model for a well-founded effect chain analysis and decision-supporting
V&V processes.

text: Im Zuge der Digitalisierung erfahren maschinelles Lernen und datengetriebene
Methoden derzeit eine große Aufmerksamkeit in Wissenschaft und Industrie. Es fehlt
jedoch an Grundlagenwissen und Verständnis, wie die datengetriebenen Methoden
der Informatik mit bewährten modellbasierten Ingenieursmethoden wie dem modellbasierten
Entwurf in der Mechatronik und Methoden der Regelungstechnik sinnvoll kombiniert
werden können, um hybride Modelle zu erhalten. Diese ingenieurwissenschaftlichen
Methoden basieren auf physikalischen Verhaltensmodellen, die eine besonders verdichtete
und interpretierbare Darstellung von Wissen darstellen und insbesondere kausale
Zusammenhänge beschreiben. Für spezifische regelungstechnische Anwendungen gibt
es umfangreiches Vorwissen in Form von bekannten Strukturen und Informationen,
wie z.B. (Teil-)Modelle oder Parametersätze, die auch bei der Anwendung von Methoden
wie dem maschinellen Lernen genutzt werden sollten. Eine solche sinnvolle systematische
Verknüpfung ist wissenschaftlich, insbesondere im Hinblick auf die industrielle
Anwendung, noch nicht ausreichend untersucht worden und sehr vielversprechend.
In diesem Beitrag werden die Ergebnisse der Nachwuchsforschungsgruppe DART – Datengetriebene
Methoden in der Regelungstechnik vorgestellt. Das Hauptziel war es, die synergetische
Kombination von modell- und datengetriebenen Methoden für regelungstechnische
Aufgaben zu erforschen und es werden alle wichtigen Forschungsergebnisse aber
auch die verwendeten Grundprinzipien des maschinellen Lernens in diesem Beitrag
dargestellt.

text: In the course of digitalization, machine learning and data-driven methods
are currently receiving a great deal of attention in science and industry. However,
there is a lack of basic knowledge and understanding of how data-driven methods
in computer science can be meaningfully combined with proven model-based engineering
methods such as model-based design in mechatronics and control engineering methods
to obtain hybrid models. These engineering methods are based on physical models,
which represent a particularly condensed and interpretable representation of knowledge
and, in particular, describe causal relationships. For specific control engineering
applications, there is extensive prior knowledge in the form of known structures
and information, such as (partial) models or parameter sets, which should also
be used when applying methods such as machine learning. Such a meaningful systematic
connection has not yet been sufficiently investigated scientifically, especially
with regard to industrial applications, and is very promising. This contribution
presents the results of the DART junior research group – Data-driven methods in
control engineering. The main objective was to investigate the synergistic combination
of model- and data-driven methods for control engineering tasks, and all important
research results as well as the basic principles of machine learning used are
presented in this publication.

text: "Nowadays ultrasound technology is established in various fields of application
like industrial production or medical technology. Besides high power ultrasound
applications like ultrasonic cleaning and ultrasonic welding, which are often
not strongly restricted regarding their weight, costs, and construction space,
there are many applications in the low to medium power range like handheld surgical
instruments, medical inhalers, or ultrasonic cutters. For the latter there is
often a strong demand for low weight and construction space and low costs to be
competitive in mass production. Another challenge that arises from the RoHS-directive
[1] is, that new ultrasonic devices should avoid the use of lead-containing PZT-materials.
Against this background there is a demand for lead-free, small and lightweight
and cost-effective ultrasonic transducers.\r\nIn many of the above-mentioned applications,
pre-stressed Bolted-Langevine-Transducers (BLT) based on lead-containing PZT-materials
are established to generate ultrasonic vibrations. These are quite advantageous
in many ways and can be built tailored to each application and even for high power
of thousands of watts. But due to the required steps during their manufacturing
process (machining parts, assembly, pre-stressing, frequency tuning, …), these
transducers remain expensive. Furthermore, due to the operation in resonance,
the construction space of these transducers is linked to their wavelength and
cannot be reduced remarkably.\r\nFor these reasons, our aim is to present an innovative
lead-free ultrasonic transducer for low to medium power applications, that is
based on bending vibrations instead of longitudinal vibrations. This design enables
to build very small transducers. Furthermore, due to their simple construction,
these transducers can be built at low manufacturing costs and are well suited
for industrial mass production. The use of lead-free piezoelectric materials makes
this transducer design ready for future applications.\r\nIn our contribution we
will present the model-based design of a lead-free 30 kHz bending transducer for
applications up to 10 W. Furthermore, the comprehensive experimental analysis
of this transducer-prototype in applications like mist generation or ultrasonic
drilling will be presented. The results will be compared to a PZT-based bending
transducer and a classical BLT to show the potential and limits of these kind
of transducers and lead-free materials.\r\n"

text: Power ultrasonic actuators are used in various industrial, automotive and
medical applications. Examples are ultrasonic welding of plastics or metal, surgery
processes like cutting of tissue or bone, and the excitation of cavitation in
liquids for ultrasonic cleaning. From a physical point of view, many of these
processes are characterised by non-constant damping conditions for the ultrasonic
actuators, since the systems need to be driven in unloaded as well as in high-loaded
states. To get high power output, the piezoelectric actuators are usually driven
in or near resonance at precisely defined vibration amplitudes. This is a quite
complicated task especially if cost or mass optimized PZT transducers are used
or if lead-free piezoelectric ceramics are applied to replace lead-containing
materials. In particular the sudden change between loading states is very challenging
for electronic excitation and control. The present contribution gives insight
into typical problems that may arise in context with sudden load-changes during
operation, e.g. uncontrolled jumps in voltage and velocity amplitudes. Measurements
on ultrasonic power actuators being abruptly immersed into water at high amplitude
are discussed for illustration. Observations during spontaneous load-changes are
explained, and it is shown that several problems may be defused by driving the
actuators in antiresonance or using a particular driving point in-between resonance
and antiresonance (“falling edge control”). The different control strategies are
investigated always using just one single hardware.
