Research of non-servo valve electro-hydraulic servo system
Proceedings of 2011 International Conference on Electronic & Mechanical Engineering and Information Technology, 2011A new non-servo valve electro-hydraulic servo system was researched. To control load, the system uses bidirectional fixed displacement hydraulic pump that is driven by AC PMSM directly drives servo-hydraulic cylinder. The hydraulic actuating unit was designed base on one design parameter and performance target.
