The paper discusses the problem of how to control a gas exchange closed ecosystem that consists of autotrophic and heterotrophic components and operates periodically in the light or in the dark. The purpose of the control is to maintain the steady state of an ecosystem with a man-oriented atmosphere. This problem of control has different solutions each of which is characterized by a set of six dimensionless variables associated with three equations--steady-state conditions. The physical characteristics of the variables and conditions of similarity of ecosystems are described. The resultant methods of control are evaluated from the point of view of economic operation of the ecosystem and the level of stability of its amosphere. The class of ecosystems for which the results obtained are valid in the event of accidental perturbations is presented. |
