The problems of automatic optimal control systems of technological complexes of grinding non-ferrous and ferrous metals as objects with insufficient and noisy software are considered. A number of key variables (process parameters) are not directly measurable, can be estimated using indirect information that contains significant interference in this problem. This requires the creation of smart devices or even entire control system on the basis of the original special mathematical methods. For automatic process control grinding systems JSC “Soyuztsvetmetavtomatika” has created the devices such as granulometer PIK-074P, which allows to evaluate particle size distribution (PSD) of ground ore, vibroacoustic analyzers of mills loading VAZM-1 VAZM-1U, VAZM-1M, which allow the assessment of the technological burden mills , the current ore grindability and predict the time of a possible overload of mills. The appearance of these intelligent devices allowed developing automated systems of optimal control processes in all types of grinding mills, which has led to the creation of intelligent control devices such as VAZM-2U, which are incorporated in the original standard control algorithms. These devices can be sufficiently adapted to other process systems. The examples of structures of automatic control systems are given in the article.
