    Opis:
    The authors present a spray booth dynamic model and a short analysis of technological factors, which may influence the dynamics of the controlled parameters. The main idea is to find robust control algorithms (mainly for temperature control), which make the process stable in any operating point. The paper presents a preliminary concept of the temperature and pressure control system dedicated for spray booths. A selected set of results of the temperature stabilization is given in the paper.

    Opis:
    In the paper, a monitoring system of a refrigeration unit is presented. This system consists of several measurement elements e.g. (pressure, temperature, energy, etc. sensors) connected using a serial RS485 network. A measurement level is a source of data for both SCADA environment and a PLC controller which are essential elements of the whole control system. The first stage of the study was related to the selection of measurement devices and a construction of a serial network. The authors also described how to link a serial 485 network with a PLC controller and how to introduce it into TCP/IP network. In the first part of the paper, there is presented a refrigeration unit as a subject of the monitoring. Then the authors describe a theoretical background needed for the energy efficiency calculation. After that the system structure with selected details about hardware integration and SCADA software implementation is presented. The final part contains selected real time experiments to show typical working modes of the refrigeration unit and to prove the efficiency of the developed monitoring system.

    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:
    Authors present a development of the temperature control system in the spray booth equipped with the two - state burner. The paper presents results of temperature control for different conditions of the external air temperature. A typical two-state algorithm isn’t enough effective to minimise temperature fluctuation amplitudes inside a spray booth. Minimisation of the number of burner ignitions with acceptable fluctuation amplitudes of the temperature is possible by means of : modification of the measurement loop, modifications of the two-state algorithm. Minimisation of number of burner ignitions will increase durability of the burner and decrease consumption fuel used to start the burner. In the final part of the article selected results of real time experiments were presented and shortly analysed.

    Opis:
    Authors present a real time supervisory system for two cooperating spray booths, which are elements of the production line. The supervisory system enables a constant observation of such physical parameters like: temperature, pressure, air flow, concentration of styrene etc. The system also warns workers inside spray booths about dangerous events like a critical level of styrene, too low overpressure, the air flow is not high enough, etc. The paper presents results of the hardware and software development.

    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.
