Mekatronisk design – Modellering og optimering af
mekatroniske systemer
Aalborg Universitet, AAU ● Fibigerstræde 16, mødelokale 1.208 ●
9220 Aalborg
Torsdag den 15. maj 2014
Today, cost-effective electronics, microcomputers, and digital
signal processors have brought space-age technology to appliances
and consumer products. Systems with precision sensors and actuators
have increased performance by orders of magnitude over what was
once possible. What sets these new, highly reliable,
cost-effective, high-performance systems and devices apart from
those of the past? Is it more than just technological advancement?
There are many designs where electronics and control are combined
with mechanical components, but with little synergy and poor
integration they become just marginally useful, error-prone,
expensive conglomeration. Synergism and integration in design set a
Mechatronic System apart from a traditional, multidisciplinary
system. So YES! There is something here! Focus in “Mekatronikdag”
will be on considering the role of mechatronics as an engineering
science to extend the current state-of-the-art regarding the design
of complex mechatronic systems.

9:45 Procesmodeller og grafisk modellering
af mekatroniske systemer i udviklingsarbejdet
Jonas M. Torry-Smith, Novo Nordisk A/S
Indlægget vil forsøge at svare på følgende spørgsmål: Hvad er de
særlige aktiviteter som et udviklingsteam skal igennem for at sikre
integrationen mellem elektronik, mekanik og software? En
procesmodel vil blive præsenteret og de enkelte steps og
aktiviteter vil blive understøttet af praktiske eksempler fra
mekatronikprojekter. Nyttige værktøjer og metoder som knytter sig
til aktiviteterne vil desuden blive beskrevet. En af metoderne til
at sikre integration i udviklingsprocessen er ‘The Mechatronic
Integration Concept’ og er en grafisk modellering af det
mekatroniske system og de interfaces, som skal sikre en god
integration mellem elektronik, mekanik og software. Den grafiske
modellering giver desuden mulighed for at beskrive
mekatroniksystemet således at teammedlemmerne kan opbygge en fælles
forståelse af systemet.

10:30 Development of new high efficient
electronic driven motor with focus on simulation tools
Hans Stougaard, GrundfosHolding A/S.Building Blocks -Mechatronics
& Power
This case will focus on how Grundfos was using different SW and
simulations tolls for development of a new generation of electronic
driven motors, where the electronic, mechanic and motor are
integrated together in a compact mechatronic design.
Grundfos is using different tools for the different technical
disciplines. In this case I will try to show, how we bring the
results together to minimize the errors between the
disciplines.
By using simulation we try to minimize test and error and to make
the solution right first time. We are also using the tools for
statically analyses and a lot of other design tasks. Therefore we
are constantly improving our design tolls and the way we are
working together. Normally we start with simple calculations,
drawings and simulation tools. Then we go to more and more advanced
tools, but on the way we will do different tests to verify the
simulations to make sure we are on the right track.
11:15 Grundlæggende optimering af en
magnetisk ledeskrue
Peter Omand Rasmussen,AAU
Den magnetiske ledeskrue har mange ligheder til den mekaniske
ledeskrue (bolt og møtrik), hvor der geares mellem roterende og
lineære bevægelser. Basalt set er tænderne i gearingen udskiftet
med permanente magneter, hvorved der opnås unikke fordele så som
reduceret slid, ingen smøring og en form for overlastbeskyttelse. I
præsentationen vil den magnetiske ledeskrue blive præsenteret,
hvorefter en grundlæggende optimering vil blive gennemgået med
forskellige hovedparametre. Slutteligt vil det blive vist, at en
optimeret magnetisk ledeskrue i visse designs vil kunne give samme
kraft som en hydraulisk cylinder drevet af et højt tryk på flere
hundrede bar.
11:35 Modelbased approach: A necessity in
optimal design of mechatronic systems
Torben Ole Andersen, AAU
To design and implement mechatronic systems there is a need for
models that support description and analysis of systems that
incorporate among other things control algorithms. The standard
procedure in industrial design is to build and test each design
concept. Much money and time could be saved in solving problems or
implementing improvements if modelling were performed early in the
design process. This contribution presents some of the mathematical
modeling/analysis skills necessary for obtaining a more “optimal”
design.

12:45 Introduction to optimization. A
foundation for a mechatronic designapproach
Henrik C. Pedersen, Aalborg University, Department of Energy
Technology
Optimization as an engineering discipline is the
formulation of design problem in terms of a mathematical
measure, which may be used as a measure for how to improve a given
design. Typically most complex systems have evolved over a
long period and a number of design iterations. This means
that improvements are often the result of a number of design
iterations based on the ingenuity of the designer and
typically involves some element of trial-and-error. Numerical
optimization methods may here be a “one-step tool” for
improving a design, hereby reducing development time and
cost. The focus of the current presentation is an introduction to
optimization as an engineering tool, which may be used in the
design of mechatronic products and systems. The presentation
starts out with an introduction of how to formulate a design
problem as an optimization problem. This is followed by a
discussion of different optimization methods, discussing both
gradient based and non-gradient based methods, and their
possibilities and limitations. Finally the presentation ends
with a discussion of the problems related to multi-objective and
mixed value problems.
13:15 Multi-level system design: A
Mechatronic design approach
Henrik C. Pedersen, Aalborg University, Department of Energy
Technology
Unlike most other engineering disciplines, mechatronics as
an engineering discipline do not relate to one specific
technical field, but is instead a multi-disciplinary engineering
problem that requires insight into how to synergistically
combine technologies optimally. Synergism and integration in the
design process is what sets apart a Mechatronic System from a
traditional, multidisciplinary system. However the typical
design approach has been to divide the design problem into sub
problems for each technology area (mechanics, electronics and
control) and describe the interface between the technologies,
whereas the lack of well-established, systematic engineering
methods to form the basic set-off in analysis and design of
complete mechatronic systems has been obvious. The focus of
the current presentation is therefore to discuss this problem and
present an integrated design approach for mechatronic
systems, which is based on a multi-level system design and
optimization approach. The presentation starts out with a
discussion of different approaches to decompose a design
problem and the implications this may have on the design
formulation. Based on a case study, the multi-level approach
is then explained and exemplified and the presentation finishes
with a summary of some of the possibilities and limitations
in the approach.

14:15 A mechatronic design of a 5MW
hydrostatic transmission for use in Wind Turbines
Daniel BeckRømer, Aalborg University, Department of Energy
Technology
In my presentation a brief overview of a hydrostatic
transmission suitable for wind turbines will be given, which
constitute a mechatronic system with anumber of components that in
itself is mechatronic subsystems. Following the transmission
overview the presentation will focus on design of fast
switching valves being a key component in the transmission where
efficient/optimum design is necessary for efficient
transmission operation. I will present a complete design method for
such valves, where the significant design aspects
areconsidered in detail. This design method shows a way of
attacking a mechatronic design task, leading the way for good
designs in complex mechatronic systems.
15:15 A mechatronic design of a digital
PTO system for Wavestar
Rico Hjerm Hansen, Wave Star A/S
The presentation will provide an insight into the design of
a digital hydraulic Power Take-Off (PTO) system for the
Wavestar wave energy converter. The PTO is the system converting
the captured wave motion into electricity and is a classic
example of a mechatronic design problem, where all aspects of
the design couples. The presentation will demonstrate how the
project has moved from a point where all possible
technologies are initially kept open to narrowing down to a
specific design using different levels of model-based
optimization. The specific design is then finally optimized and
I mplemented. A demonstration of the prototype is then given
afterwards at the full scale PTO test f acility at Aalborg
University.
