A nonlinear position tracking controller with a disturbance observer (DOB) is proposed to
track the desired position in the presence of the disturbance for electrohydraulic actuators …

The position control system of an electro-hydraulic actuator system (EHAS) is investigated in
this paper. The EHAS is developed by taking into consideration the nonlinearities of the …

As a type of hydraulic rotary actuator, a helical hydraulic rotary actuator exhibits a large
angle, high torque, and compact structure; hence, it has been widely used in various fields …

This work presents the application of a friction compensation scheme to the trajectory-
tracking control of a pneumatic servo actuator. Such scheme is based on a continuous …

Electro-hydrostatic actuators (EHAs) are hydraulic actuators with high power-to-weight ratios
that exhibit low energy loss. Thus far, methods for determining the characteristics and …

Abstract The Electronic Servo-Valve Hydraulic (ESVH) actuator is commonly used in the
