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. Client PC C IP Camera PLC CP P-1015 Regulator Server S vlab.fs.ccvut.cz Real Mode el 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.
