Modeling and experimental validation of a 2D electro-hydraulic servo proportional valve by bond graph

The two-dimensional (2D) valve, which integrates the pilot and power stages into the spool, offers large flow and high power-to-weight ratio, making it widely used in military and aerospace applications. However, existing 2D valve models based on linear theory struggle to capture its nonlinear chara...
