Enhancing functionality of two-rotor vibration machine by automatic control

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.
