Future development of electro-hydraulic servo control systems will primarily focus on the following areas:
(1) Integration with electronic and computer technologies. As electronic components become more integrated, interfaces and fieldbus technologies are increasingly applied to system control, enabling the creation of high-level information systems. Furthermore, the deep integration of artificial intelligence (AI) computing power with hydraulics and electronic controls is a key trend; this drives the evolution of traditional hydraulic components through smart technologies, facilitating the transition from conventional manufacturing to intelligent hydraulic solutions. For instance, the deep integration of electro-hydraulic servo control and smart technologies enables features such as high system integration and remote operation.
(2) Greater emphasis on energy conservation and efficiency. Technologies such as variable frequency drives and load-sensing systems will significantly boost overall system efficiency. These technologies are already being implemented in equipment; the use of electric drives and integrated power packs, for example, helps reduce energy consumption compared to traditional systems that rely on centralized pump stations for fluid supply.
(3) Extensive research will be conducted on novel electro-hydraulic components and integrated sensing elements, such as high-precision, contamination-resistant direct-acting electro-hydraulic control valves, hydraulic converters, and electronic hydraulic pumps.
(4) Computer technologies will be widely applied in the design, modeling, and simulation testing of electro-hydraulic control systems. Tools and systems such as CAD (Computer-Aided Design), CAE (Computer-Aided Engineering/Analysis), CAPP (Computer-Aided Process Planning), CAT (Computer-Aided Testing), and CIMS (Computer-Integrated Manufacturing Systems) will play an increasingly significant role throughout the lifecycle of electro-hydraulic systems.
(5) New materials-such as electromagnetic materials and polymers-as well as wireless proportional remote control systems for electro-hydraulic applications, will see further research and implementation.
