Opis:: In the paper, a comparative analysis of control algorithms in the temperature control system for spray booths is presented. Additionally, basic technological limits which may have some influence on the quality of control are described. From technological point of view, a typical spray booth operates in two modes i.e. coating and drying, which are related to different temperature work points. In practice, it is the main reason of changes in plant dynamics, precisely changes in dynamical parameters of the spray booth. The authors analyzed other technological factors which might disturb the temperature inside the booth and finally make a painted covering worse or even useless. The main idea was to find robust control algorithms, mainly for temperature control, which make the process stable in any working point. In the final part of the paper, selected real time experiments are presented to show typical working modes of the spray booth and to proof the robustness of the developed and implemented control algorithm.

Opis:: The authors present a concept of the temperature control system for a spray booth equipped with a single burner. The control system uses PWM modulation with dynamic trigger time periods. The paper presents the results of temperature control simulations for different conditions of external air temperature as well as the analysis of external air temperature and trigger time period impact on temperature fluctuation amplitudes inside the spray booth. A dynamic trigger period will minimize the number of burner ignitions with acceptable fluctuation amplitudes of temperature. The minimization of the number of burner ignitions will increase the life time of a burner and decrease the fuel consumption used to start a burner.

Opis:: The paper presents an internet system to manage 230 V electric devices in computer server rooms. The system is realized as the power strip connected to one of servers through the USB port. The system allows for the real-time temperature measurement and provides the maintenance-free operation. Moreover, it allows to turn on or off the connected devices using information from temperature sensors. Also it is possible to turn on or off every single socket disregarding temperature. The user communicates with the system through the web browser, and no dedicated software is required on the client side. The system has been installed and verified experimentally.

Opis:: Laboratory tests of temperature control systems are often time consuming processes. This condition results from large time constants of real electrothermal devices. One of possibility of reduction the time value required for tests lays from utility of analogue models. Such models are characterized by possibility to unrestricted formation of time scales of voltage and current wave shapes. According to this advantage, temperature process in real device can be significantly accelerated. In the article the universal Beuken model, coupled with control and recording system implemented in PLC controller was presented. The model can be used in selection of optimal parameters of temperature controller process. The ability of transient characteristics recording and comparing provides ease selection of proper regulator and location of temperature sensor, adapted to specific solution.

Opis:: Remote temperature sensing and thermal imaging systems [1, 2] are invaluable tools in various fields of science and technology. The fact that radiation is a function of object surface temperature makes it possible for remote temperature measurement systems to calculate this temperature. However, to measure temperature accurately with IR system, it is necessary to know emissivity. Emissivity is one of the major sources of error in radiometric measurements. Generally, emissivity is not constant as it depends on several parameters: temperature, viewing angle, wavelength, contamination or roughness. The article presents a laboratory heater which can be used to measure the thermal emissivity ε depending on the sample surface topography.

In the first section a survey of more important papers developed to temperature control and controllers based on results carried out at the Division of Automation is presented. In the second section it is proposed to employ a process model M purposely accelerated with respect to the actual process P in a Model Following Control system. Such a solution provides good tracing properties, good suppression of disturbances and reduces the impact of perturbations.

Opis:: This paper is aimed at the description of hardware design, software equipment and the functionality of the second evolution of the intelligent multipurpose input/output microcontroller converter and control unit designed and assembled by the authors. Preceding stages of the unit development are concisely overviewed first, the deficiencies of which give rise to the primary motivation of this contribution. Then separate hardware parts of the novel unit are described in detail including electronic schematic diagrams. The device firmware and software capabilities are introduced as well. The advantages of the unit are highlighted compared to older versions. Its functionality, performance and efficiency are then verified by a laboratory control-related dynamic responses measurement example. In the contrary to previous evolutions, a more compact hardware design, increased A/D and D/A converter resolutions, added USB communication capability, better and more accurate analog circuits with more advanced operation amplifiers, the use of OLED instead of LCD display, the pulse-width modulated signal generated by the microcontroller unit itself can be considered among the most important improvements. Moreover, the direct use of the serial link may reduce noise significantly and makes the device more universal.
