This paper addresses the development and experimental validation of a digital control system for the electric drives of grain-cleaning machine working units based on the SAKO SKI780 frequency converter, the Arduino Uno microcontroller platform and the Modbus RTU communication protocol. The proposed system is intended to improve the accuracy, flexibility and reliability of electric-drive control during grain-cleaning operations. The general architecture of the control system, the principles of interaction between its main hardware components, the control algorithm for generating and transmitting commands through the RS-485 interface, and the corresponding software implementation of the microprocessor-based control system are presented.
Particular attention is paid to ensuring stable and reliable data exchange between the microcontroller and the frequency converter, as well as to the correct formation of control commands for regulating rotational speed and other operating parameters of the electric drive. The developed software makes it possible to set the required operating modes, transmit control signals, process feedback data and coordinate the operation of individual machine units. Experimental studies confirmed the stable operation of the proposed control system and its ability to accurately reproduce specified speed modes under varying load conditions.
The obtained results demonstrate that the use of digital control makes it possible to reduce transient response time compared with conventional analog control methods, thereby improving the stability of electric-drive operation and the consistency of grain separation. The developed system also provides flexible adjustment of rotational speed and facilitates centralized control of individual working units. The proposed approach can be considered a promising solution for the automation and modernization of grain-cleaning equipment. Further development may involve the integration of sensors for monitoring grain quality, drive load and material flow, enabling adaptive control algorithms and automatic adjustment of operating parameters in response to changing technological conditions. The obtained results provide a scientific and practical basis for improving the energy efficiency, reliability and technological performance of modern grain-cleaning machines.

Technology, energy, agriculture transport AIC is a scholarly professional journal with a long-standing history and stable academic tradition, reflecting the evolution of engineering and technical sciences within the agro-industrial sector of Ukraine.
The journal was founded in 1997 under the title Bulletin of Vinnytsia State Agricultural Institute. According to the Resolution of the Presidium of the Higher Attestation Commission of Ukraine dated September 11, 1997, the publication obtained the status of a professional scientific journal, which enabled the publication of the main results of doctoral and candidate dissertations in technical sciences. From its inception, the journal positioned itself as an academic platform for addressing current issues of mechanization, electrification, and technical support of agricultural production. During 2001–2014, the journal was published under the title Proceedings of Vinnytsia National Agrarian University. Series: Technical Sciences (State Registration Certificate of Print Media KV No. 16644-5116 PR dated April 30, 2010). Throughout this period, a systematic approach to the selection and peer review of scientific manuscripts was established, the thematic scope of publications was expanded, and continuity of scientific directions as well as the development of sectoral engineering schools was ensured. Since 2015, the journal has been published under its current title, Technology, energy, agriculture transport AIC (State Registration Certificate No. 21906-11806 R dated March 12, 2016). The change of title reflected the expansion of the journal’s thematic coverage and its orientation toward interdisciplinary research in mechanical engineering, energy systems, electrical engineering, transport technologies, automation, and digital solutions for the agro-industrial complex.
