Diordijev V. Improvement of control systems for electrotechnological complexes based on the small-size feed-mix production plants

The thesis is devoted to the solving of scientific and applied problem of the theoretical justification for the creation of control systems and electro-functioning systems for the production of feed-mix in the agricultural sector and developing of the means for their implementation. On the basis of the performed theoretical and experimental investigations the choice of the generalized vector control criterion electron for electrotechnological complex was established with taking into account the stage of the farm economic development strategy prognosis, the selection or synthesis of the optimum functional structure for small-size feed-mix plant, the preparation and implementation of the executive recipes. Additionally, the automated electrotechnical complex generalized and linearized structure was designed; the mentioned complex theoretical studies allowed determining of the system's control and regulation parameters, which was the basis for substantiation and system integration for complex of technical devices as well as for automatic technological complex software implementation and development. The set of the integrated mathematical models was obtained with the respect of flexible production models, the system engineering, the decision-making and continuous algorithm support for non-linear object, which being combined makes provisions for adequate feed-mix manufacturing for farming conditions directly with usage of local ingredients, considerable expenditure decreasing and the possibilities to get feed-mix of adequate combination, quality any quantity any time. The performed experimental studies and economical calculations have confirmed the efficiency and fairness of the developed theoretical propositions.
