Abstract

Abstract: The Fourth Industrial Revolution, driven by information technology, is propelling industrial transformation and ushering in the era of intelligence. Due to the widespread application of hydraulic systems as core power and control components in advanced manufacturing, aerospace, marine and other major equipment, the intelligence of industrial equipment inevitably requires the realization of intelligent hydraulic components and systems. So, in recent years, intelligent hydraulic system has been a research hotspot in the hydraulic field, driving the hydraulic field into the intelligent era and bringing new vitality to the research of hydraulic systems. However, it has also encountered new challenges, including inconsistent understanding of intelligent hydraulic systems, lack of comprehensive research on systems, and fragmented breakthroughs. The connotation and evolution process of intelligent hydraulic systems are analyzed, the architecture of intelligent hydraulic systems is elaborated, the three major characteristics of intelligent perception, intelligent control, and intelligent maintenance of intelligent hydraulic systems are summarized, and the research progress at home and abroad from above three aspects is summarized, revealing the problems and challenges of intelligent hydraulic systems; Finally, the research path and development trends to address the challenges are discussed.
