Combined feedforward/disturbance observer-based control of pump-controlled electro-hydrostatic actuation system

Active Disturbance Rejection Control for Double-Pump Direct-Driven Hydraulics

“…Then, when addressing the problem of flow imbalance, the time-varying and nonlinearity of the pump-controlled system also need to be solved. Hence, many control methods were proposed, such as adaptive fuzzy control [13], control based on disturbance observer [14,15], adaptive backstepping control or iterative backstepping control [16][17][18].…”
