Optimum control of closed ecological systems: mathematical aspects
1Institute of Biophysics, Siberian Branch, Russian Academy of Sciences, Krasnoyarsk, Russia.
Abstract:
Optimum control of a closed ecological system (CES) is not possible without adequate CES description and appropriate evaluation of factors, which act upon the system and introduce additional errors and uncertainties into the forecast of the CES state. The statement about key significance of stationary state consideration for further CES development is supported. In this article some of the disturbing stationary state factors and the contribution of them to CES state formation are considered. An approach to outlining the optimum set of chemical elements--the balance of which has to be calculated--is presented. An example of the minimum description of CES stationary state is considered.

An open-loop control system operates without feedback from the output. It consists of two primary elements: the controller and the controlled process. The controller receives an input signal and...

Feedback control systems
Linear feedback systems are theoretical models that simplify analysis and design. These systems operate under the principle that their output is directly proportional to their input within certain ranges. For instance, an amplifier in a control system behaves linearly as long as the input signal remains within a specific range. However, most physical systems exhibit inherent nonlinearity...
