Indispensable for Production
The Department of Instrumentation and Control Engineerign was established in 1998 by
a merge of the Department of Electrical Engineering, Department of Precision Mechanics
and Optics and the Department of Automatic
Control. The present three divisions in mutually
beneficial cooperation participate in the curricula of a 3-year bachelor study programme:
“Information and Automation Technology“,
2-year master study programme for bachelor
graduates: “Instrumentation and Control Engineering“ and doctoral study programme: “Control and Systems Engineering“. In addition to the basic study programme the staff of the department is engaged in lecturing on subjects: Computer aided study, Electric
circuits and electronics, Electrical machines and drives, Automatic control, Measurement in Engineering and a number of other subjects in further fields of study of the bachelor and master study programmes.
Centres of Competence
Our department participates in the
work of the following Centres of
Competence:
Centre for Applied Cybernetics:
www.c-a-k.cz
Centre of Vehicles for
Sustainable Mobility:
www.cvum.cz
Cooperation of Students with Firms
Paid cooperation concerns investigation
of partial issues both during the semester
and in the form of a summer voluntary
job. Such cooperation, if successful, can
develop into an application/research
task for a thesis and potential employment by the cooperating company.
Within the scope of the EU project SEAT (Prof. Ing. Tomáš Vyhlídal, Ph.D.,
Prof. Ing. Pavel Zítek, DrSc.) a concept of local temperature and relative air
humidity control around passengers in airliners was designed and laboratory
tested (see Fig.)
The concept assumes installation of a feed and exhaust
nozzle in the back of the seat
in front of the passenger. The
ventillation system modified
in this way will make it possible to create for the passenger a local microclimate
and thus maintain the value of
relative humidity at a higher
level compared with that in
other parts of the airliner´s
passenger cabin.
Simulation and laboratory assessment of the concept
of local control of temperature and relative humidity
around the passenger in an airliner proposed in the
EU project SEAT.
Artificial Intelligence
A relatively strong group comprising two divisions dealing with artificial intelligence (AI) is active at the department. The first division (Ass. Prof. Ing. Ivo
Bukovský, Ph.D.) is a research team dealing with adaptive processing of signals and informatics for control (newly knows as ASPIC – Adaptive Signal
Processing and Informatics for Control). The group is focused on the development and implementation of adaptive algorithms for modelling, control and
real-time monitoring of dynamic systems and applications in informatics.
Members of the division participate in international cooperation, in international research visits and in professional communities (e.g. IEEE Computational Intelligence Society).
The second division (Prof. Ing. Jiří Bíla, DrSc.) is oriented towards fuzzy
modelling and expert systems. The main topics are interpretation of artefacts in the theory of resolving tasks and detection of emergent situations
in expert systems. Interest is concentrated on extensive environmental systems (area around Třeboň) and on expert systems (large industrial sites, e.g.
TOS Varnsdorf, where members of the group monitor their colleagues from
TU Liberec). The division developed its own theory of treating emergent
situations, published a number of papers on this topic and in 2013 organized
(together with VŠB TU Ostrava) the Prague Symposium on Expert Systems.
DEPARTMENT OF INSTRUMENTATION
AND CONTROL ENGINEERING
Control Laboratory Accessible
from Home
At the Faculty of Mechanical Engineering
of the Czech Technical
University in Prague
(CTU in Prague) the
INTER
RNET
Automatic Control
Laboratory serves for
verification of theoretical knowledge
from the field of logic,
analog or numerical
control. The laboratory is comprised Diagram of Communication System
of physical models
equipped with state of the art control, information and communication equipment. In addition to this real laboratory a virtual laboratory (http://vlab.fs.cvut.cz) open to the public in several languages
was established. It contains models of tasks from the real laboratory.
Experiments with various control units, monitoring of the time behaviour of quantities, assessment of selected characteristics both in the
time and frequency domain can be performed on virtual models by
animation, visualization and simulation. The virtual laboratory also
makes it possible, using an ordinary internet browser, to control, in
real time, the selected task. It is also possible to select a specific type
of controller, to monitor the behaviour of the task with a webcam
(see diagram of the communication system), and to record the time
behaviour of quantities of the control circuit.

High-Speed Permanent Magnet
Synchronous Machines
An extremely challenging and necessary field is the design and
control of high-speed permanent magnet synchronous machines
(Ass. Prof. Ing. Martin Novák, Ph.D., Ass. Prof. Ing. Jan Chyský, CSc.,
Prof. Ing. Jaroslav Novák, CSc.). Compared with classical “low-speed“
machines high-speed machines offer above all a considerably higher
power density, i.e. the ratio of the output power of the machine to
its volume or mass. At present the high-speed permanent magnet synchronous machine designed
at the department gives
an output of 300 W and
100.000 r.p.m with a goal
of 3 kW and 250.000 r.p.m.
More information on the
project and on hitherto
achieved results are available on website http://control.fs.cvut.cz/pmsm
How to Produce Special Components?
Ass. Prof. Ing. Jan Hošek, Ph.D. and his team are oriented towards special
technologies necessary for the production of optical and mechanical instruments and systems. Various untraditional materials and techniques are of
interest for the manufacturing of measuring devices and complex systems
even from with standart technologies hardly machined materials. The team
deals with micromachining with conventional tools and also with electric
discharge machining (EDM). This enables machining not only from poorly
machinable steels
but also from molybdenum, tungsten,
carbon composites
and other materials
with special properties. Besides driling
holes with various
shapes, volume micromilling can be
performed (see Fig).
The smallest dimensions of the details
are in the range
around 10µm.
Accurate Measurement
Ing. Šárka Němcová, Ph.D. from the Division of Precision Mechanics and
Optics is engaged in optical measuring methods. Concerned are contactless noninvasive methods of the measurement of mechanical and optical
properties of materials, specimens and components. At present at the laboratory of the wave optics the topography of a piezo-excited deformable mirror by topographic interferometry is measured.
Deformations within the
range of fractions of the
wavelength of the applied
radiation, i.e. in the order
of tenths of micrometers,
can be measured by this
method.
Cultivation Equipment for Microphytes
Ass. Prof. Ing. Josef Zicha, CSc. and Ing. Karolina Macúchová designed an
equipment for phototrophic cultivation of microalgae according to an assignment from the Microbiological Institute of the Academy of Sciences of the
Czech Republic. Microalgae can be used for biodegrading waste water and
for collecting CO2 from industrial waste or as a source of biofuels. The picture
shows a working cultivator at the Microbiological Institute at the Opatovický
Mlýn locality near Třeboň.
