The aim of the work is to find complex solution to the problems of technological processes digital transformation by researching their mathematical models and new adaptive digital signal processing methods integration that can provide innovative development.
There was described the way of grain drying process control adaptive automatic control system design in the paper. Researched process is characterized by non-stationary and stochastic characteristics of the object and environment. To solve this problem, the method of minimizing the optimally weighted sum of symmetric correlation functions was chosen. There were obtained unbiased and efficient estimates of the parameters of the transfer functions of the dryer. It allowed to implement optimal adaptive algorithms for autonomous control of individual channels of temperature and humidity of the dryer as a multidimensional object with cross-links.
A reaction-convection-diffusion equation was researched as a mathematical model of a number of physical and technological processes. A complete group classification of the symmetry properties of the (1+2)-dimensional reaction-convection-diffusion equation was carried out to within equivalence transformations and also problem of finding of nonlocal equivalence transformations of a system of nonlinear convection-diffusion equations was solved.
One of the tasks considered in this paper is the necessity to provide accurate data that describes the technological process. To solve this problem the adaptive methods of digital signal processing were designed. They make it possible to determine the useful signal in the case it was distorted by external factors. Designed methods also allow to obtain the predicted values of the monitored signal. The implementation of the designed methods is carried out using modern programming languages.
There was also researched the innovative component, which is one of the systemic factors of technological change and development of the state in the paper. Methodical bases of information and analytical support of innovative development determinants and stages of their consecutive realization influence estimation are offered. The algorithm for the design of the unified system for monitoring of the state innovative development in terms of digital transformation is proposed.
