Abstract: A digital compensator using a forward algorithm, F(z−1 ), and a feedback algorithm, H(z−1 ), is developed for an electrohydraulic position control system incorporating an underlapped servovalve ...

Abstract: The transient response of an electrohydraulic servovalve coupled to an axial piston ball motor is analyzed. In particular, the effect of long lines between the servovalve and motor is studied ...

Abstract: The effect of a return line orifice on the steady-state performance and dynamic characteristics of a servovalve flapper/nozzle stage is investigated. Generalized design characteristics are initially ...

Abstract: The open-loop response of servovalve-controlled single-rod linear actuators in investigated for both the extending and retracting cases. A linearized frequency response technique is used to establish ...

Abstract: This paper analyzes the pressure distribution, leakage, force, and torque between the barrel and the port plate of an axial piston pump. A detailed set of new equations is developed, which ...
