Control system and optimization of parameters of a closed biosystem the size of a pico-satellite

Publication Date Nov 28, 2020

Abstract

The paper researched the sustainable functioning of the closed self-regulating biological system based on macrophytes Fucus vesiculosus, Fucus inflatus, Laminaria saccharina and Chlorella vulgaris. The authors describe the methods and apparatus for monitoring the composition and control of biological experiments with such a system, which is offered to spend on board the International Space Station (ISS). We also consider the option of the experiment on board the small satellite. The main task of automatically controlled experiment is to ensure the long-term functioning of the isolated biological system under conditions of weightlessness. Based on the analysis of the interaction structure of the main components of biological systems under study was developed a mathematical model of a closed biological system on the basis of aquatic organisms and holds its computer simulation, with which defined the conditions for the forecast can be carried out and state control investigated the conditions of maintaining it stable life. We consider the automated control system of a biological system, providing its stable operation. The main indicator of the functioning of biological systems encouraged to use the amount of oxygen in the air section and dissolved in water. As a biological control system parameters used by the lighting level and temperature of the water environment. In the experiment on autonomous spacecraft (microsatellite) proposed to manage the dampers in the heat-insulating sheath. The dependencies for defining the threshold...
