The influence analysis of the substrate heating time on the optimal duration of the fermentation process in the digester of a biogas plant (BGP) is carried out. The application of the efficiency criterion of the BGP operation to determine the optimal time for the end of the fermentation process in the digester is substantiated. The relevance of the research is because the optimal moment for fermentation process completion of the substrate corresponds to the maximum productivity of the process for the target methane product.

The researches results of the automated control system improvement for a thermoelastic press in the implementation of the processes of isothermal deformation and metallic materials stamping in a state of superplasticity are considered. It is established that the deviation from the optimal temperature-speed deformation regimes leads to the defect formation in the article body in the form of sinks, clamps, oxide films drawn into the article from the surface of the semi-finished product. These defects are stress concentrators that can lead to the destruction of loaded parts. The main problem that prevents the active industrial use of automated control systems for considered equipment is determined — their inertia. Measures to eliminate the inertia of the automated control system for thermocompression plants are proposed. It is shown that the main and most effective method for solving this problem is the use of digital extropolation algorithms for short-term prediction of the measuring and control system behavior. The improved automated control system has been successfully tested at stamping of finned aircraft panels and shells made from aluminum alloys D16, V95, V96ts, 01420. The system provided control of the temperature and speed parameters for metal materials stamping in the state of superplasticity and under isothermal stamping conditions with a heating accuracy of 2... 4 °С and the accuracy of the speed parameter compliance (deformation rate) up to 0.1 mm/s. Keywords isothermal forging, thermal compression, thermal expansion, defects, automated control system, system inertia
