In mobile hydraulic systems, velocities are typically not measured. However, using their
reliable estimates for feedback is known to allow designing better control laws. We are going …

Automation of various agricultural tasks, which are nowadays routinely executed by
operators of hydraulically actuated tractors equipped with front-end loaders, is an important …

A second order sliding mode control design for a mobile hydraulic system, including
bounded model uncertainties and external disturbances, is the subject of study. The …

A problem of position control of a forestry crane is studied. Several features of industrial
hydraulic systems are pointed out, namely a nonlinearity of a valve and a pressure …

Hydraulic manipulators on mobile machines, whose hydraulic actuators are usually
controlled by mobile hydraulic valves, are being considered for robotic closed-loop control …

Due to some limitations of mechanical solution for automation of front end loaders,
specifically self-leveling task, we investigate here the sensor-based solution. We present a …

ABSTRACT A growing population is driving automatization in agricultural industry to strive
for more productive arable land. Being part of this process, this work is aimed to investigate …

We present a sliding-mode-based control design for a telescopic link of a mobile-hydraulic
forestry crane under bounded modeling uncertainties and external disturbances. Mobile …

A problem of position control of a single-link hydraulic drive, including model uncertainties
and disturbances, is studied. Main properties of mobile hydraulic systems are taking into …
