Using the Takagi-Sugeno approach, the task of managing the information process is formulated. The use of qualitative information makes it possible to move from a combined model of information process management to a generalized model. The fuzzy tracking model and the control law are formulated. The algorithm of tracking control is developed.

Studies have been carried out to determine the dispersion and chemical composition of dust in asphalt concrete plants during the process of preparing the asphalt-concrete mixture. Experimentally defined parameters are necessary for the development of methods for dispersing particulate matter in the atmosphere and for developing a set of measures for dedusting production processes in order to ensure the required level of labor safety. The results of X-ray spectral microanalysis of dust and mineral powder released in the production zone of asphalt concrete plants are considered. The method of electron-probe x-ray spectral microanalysis is used to measure the weight concentration of chemical elements in microvolumes of solid inorganic materials and asphalt concrete samples and is necessary for solving the labor safety problem.
