USING DIGITAL ELECTROHYDRAULIC SERVO VALVES IN FLUID CONTROL SYSTEMS

摘要

The authors present the structure and the performance of an original test bench designed in order to point out the accuracy, flexibility and stability of the digital control solution. The digital assembly is tested in parallel with an analog one in a harsh electromagnetic environment. This new type of controller area network is best suited for multipoint, long range cabling in high electromagnetic interferences areas where analog feedback signals may fail. This new type of control is already used in military, automotive and aerospace simulating platforms or other systems where precision is very important.
