“…At the same time, the vibration-transformed function depends on the phase difference β 1 − β 2 . This is essential for the possibility of control; in particular, for vibrational process machines [Fradkov, 2007;Blekhman, 2012;Andrievskii et al, 2016;Fradkov et al, 2016;Tomchina et al, 2018;Tomchina et al, 2021;Tomchina, 2022] , when the function F represents a characteristic of the process (see Sec. 4).…”

Oscillations of arguments in non-linear dependencies change the average values of respective functions. As the simplest example, the harmonic oscillations of the ball radius increase the average volume and surface area, while the average radius remains unchanged. Despite their elementary nature, such considerations are often ignored, which may lead to inaccuracies and errors. This paper presents a study of such effects in algebraic, geometric and trigonometric relations, as well as in certain basic formulas of mathematical analysis. A number of applications in solving technical problems are considered; in particular, the influence of parameter oscillations on the efficiency of industrial operations. The results of the study may be of interest for the theory of vibrational processes and devices, and the theory of accuracy, as well as for the theory of control and optimal processes.

“…Several studies focused on the control of the two-rotor vibration machine have tackled issues like operation during resonant modes, speed, and phase shift synchronization. For instance, [Gorlatov et al, 2015] and [Tomchin et al, 2021] present the results of the speed gradient algorithm for reaching the Sommerfeld frequency. This algorithm has also been tested for multiple-speed synchronization [Shagniev et al, 2022;Tomchina, 2023].…”

The demand for the development of cyber-physical systems remains high across various production sectors. While some industries have made significant strides, others still require ongoing research and development efforts. This article delves into the application of feedback control for equipment in the processing industry, using a two-rotor vibration machine equipped with induction motors as a case study. Conventionally, such equipment is manually operated with the help of affordable constructive facilities, which does not align with the principles of Industry 4.0. In response, this paper explores an architecture for an automatic control system capable of handling various technological tasks, including mixing and transporting processed media. This architecture encompasses several components, such as real-time regulator tuning, control of the rotor speed loop, and/or adjustment of the phase shift between the rotors based on machine sensor measurements. A notable advantage of this control system lies in its complete software-based implementation. The article also presents the findings from full-scale experiments, demonstrating the capabilities and effectiveness of the proposed approach.
