Research on Embedded Electro-hydraulic Proportional Valve Controller

In this paper, a high-performance electro-hydraulic proportional valve controller is designed and developed by using embedded-computer technology. Based on the analysis of the work principle and control requirements, authors present a structure of the controller and its control strategy, and its design and program method are discussed in detail. This controller has advantages such as simplicity, powerful function, flexibility and high performance price ratio, has been a renewal product and affords a new choice for users in industry.
