The International Conference on Mechatronics, Automation and Intelligent Control (MAIC) has confirmed once again this year the enthusiasm and determination of students and young researchers to play a major role in the scientific progress. Since 2021, we have regularly gathered to discuss the most recent developments and achievement on mechatronics, automation and intelligent control, and we firmly convince that sharing our expertise and experience is the foundation of research activity.The 2023 3rd International Conference on Mechatronics, Automation and Intelligent Control (MAIC 2023) took place from September 15th to 17th, 2023 in Guilin, China (virtual event), attracting about 80 leading delegates from around the world. The format we chose is a formal meeting primarily aimed at graduate students and leading researchers, who were encouraged to present their work through oral or poster presentations that provide genuine engagement of the audience and cross-pollination of ideas. One of the main purposes of the Conference was to create an international network of researchers, both experimentalists and theorists, and fruitful collaborations across different branches of mechatronics, automation and intelligent control.After previous two sessions that strengthened it, the International Conference on Mechatronics, Automation and Intelligent Control was held for the third time. It was a three-day Conference. The success of this year’s event was testified by an increased number of participants and institutions all around the world. This resulted in an extremely rich and interactive keynote speech, oral and poster session that covered several areas related to mechatronics, automation and intelligent control.With the intent of broadening the contents and stimuli adopting academic communication, the keynote speech part was held. This choice reflected the growing importance of the activity performed by scientists and researchers, especially at the earliest stages of their career, as a way of increasing their expertise and developing soft skills. During the meeting, Prof. Xingjian Wang from Beihang University, China shared with us his research on Fault Diagnosis and Fault-tolerance Control for Aircraft Control System. In order to realize the highly reliable and healthy service of the aircraft control system, the health status assessment and remaining useful life prediction of the key components of the aircraft control system, the key technology of fault diagnosis for the airborne hydraulic system, and the high safety hierarchical active fault-tolerance control strategy were carried out to effectively improve the healthy service capability of the aircraft control system.This paper volume cover topics on Industrial Robots and Automatic Production Line, Automatic Control Technology, Intelligent Fault Detection and Identification, Man-Machine Interactions, etc. Given the recent experimental achievements in mechatronics, automation and intelligent control, several contributions were focused on the latest results obtained in these fields, presenting the impact of experiments to the community of young researchers and forecasting the future goals in these areas of research.The organizers of MAIC 2023 would like to thank all the keynote speakers, authors, peer reviewers, and everyone who contributed to the Conference. We owe gratitude to all the Committee members for providing necessary help and support throughout the meeting.
