Research and application of speed stability of flow stabilizing valve in direct-drive electro-hydraulic servo system

International Journal for Simulation and Multidisciplinary Design Optimization
When the direct-drive electro-hydraulic servo system is used for position control of hydraulic actuators, load unbalance or external disturbances can cause flow imbalance, leading to poor speed stability of the actuator and thus reduced position accuracy.
