Synthesis of a control system for the process of diesel fuel hydropuring with the Adar method

Currently, one of the main important tasks at oil refineries is to increase their productivity and product quality. Hydrotreating of diesel fuel is important in the oil refining process. The main purpose of hydrotreating is to improve the quality of fuel and remove sulfur, nitrogen and oxygen compounds from it. The diesel fuel hydrotreating process has a significant impact on product quality. As an object of study, a chemical reactor has a nonlinear characteristic and has the property of a reverse chemical reaction during the hydrotreating of diesel fuel. Also, the diesel fuel hydrotreating process is considered a nonlinear and multidimensional control object, and all its parameters cannot be measured online. Therefore, a mathematical model was developed that takes into account the features of the technological process that arises when creating a highly efficient control system. The article deals with the synthesis of effective algorithms for controlling a chemical reactor and developed a synergistic controller for a class of indefinite nonlinear dynamic systems. The synthesis of control laws is performed by the method of analytical design of aggregated controllers (ADAR).
