This paper considers the process of preparing a mixture that can be used to optimize the production of food and fuel ethanol. An automatic system for optimal control of the mixture preparation process has been developed, based on measuring the consumption of raw materials and the concentration of the mixture, as well as regulating the water supply. The proposed controller maintains the required mixture level by changing the flow rates. By changing the flow rates of the components, the optimal controller maintains a constant mixture concentration and stabilizes the flows. The developed improved optimal controller is based on robust control of a nonlinear process, which ensures more stable system operation, improved quality of the mash and the final ethanol product, smooth transitions between modes, and energy savings.
