Abstract
The study is targeted at developing the structure of automatic control system (ACS) for indoor air quality and comfort management. Automatic control problem has been formalized as a multi-criteria optimization. The modern methods of assessing the safety of the gas composition in the air have been analyzed. As follows from the analysis, it has been established, that the synthesis of automatic control system requires application of analytical safety indicators for accurate mathematical modeling of the ship premises microclimate. The requirements for the gas composition in the air have been formalized. The obtained analytical dependences have been included into the mathematical model of the room microclimate. An alternative approach for the air quality and comfort management has been developed. The article contains the design of the mathematical model of the ship premises microclimate considering
analytical functions for gas composition in the air and air quality. The structural scheme of the automatic control system has been proposed and the automatic control problem has been defined through the multicriteria optimization. The following areas for further research have been identified: verification of the model, particularization of the ACS structure and development of a control algorithm, creation of a prototype on a microprocessor elementary base. The obtained results of the research can be applied when modeling the dynamics of indicators of comfort and safety of room microclimate as well as when creating automatic control systems.
