Hydraulic Synchronization Control Research Status and Outlook

With the hydraulic synchronization control system in the industrial field of application is gradually widespread, synchronization control research is also more and more attention. Based on this background, this paper combines the current research status of hydraulic synchronization control system, from three aspects of the hydraulic synchronization system to discuss: 1) hydraulic synchronous drive system: analysis of the mechanical rigid synchronous drive system, hydraulic balance synchronous drive system, electro-hydraulic servo synchronous drive system three kinds of control, and summarize the advantages and disadvantages of the different control methods; 2) electro-hydraulic servo synchronization control strategy: master-slave synchronous control, equivalent synchronous control, cross-coupling synchronous control; 3) electro-hydraulic servo synchronous controller: PID control, adaptive robust control, neural network control; Finally, according to the analysis of the above three aspects of the research, the hydraulic synchronization control system outlook, the future of the hydraulic synchronization technology and electrical, Internet and other technologies integrated with each other, so that its control accuracy and response speed will be greatly improved and will gradually be applied to a number of applications. The future hydraulic synchronization technology and electrical, Internet and other technologies are integrated with each other, so that its control accuracy and response speed will be greatly improved and will be gradually applied to some high-precision industries, in order to promote the hydraulic synchronization control technology in the industrial field of research and application of reference.
