This research deals with master-slave control of a teleoperated hydraulic construction robot. In this system, the master consists of two joysticks, and the slave is the hydraulic construction robot (including the fork glove, boom, arm, and swing, driven by hydraulic actuators). In a previous research, the authors proposed a force feedback method based on position-velocity control, in which the ...

A novel model-based controller for 6 degree-of-freedom (DOF) hydraulic driven parallel manipulator considering the nonlinear characteristic of hydraulic systems-proportional plus derivative with dynamic gravity compensation controller is presented, in order to improve control performance and eliminate steady state errors. In this paper, 6-DOF parallel manipulator is described as multi-rigid-bod...

This paper describes the design and implementation of an automatic hydraulic circuit design system using case-based reasoning (CBR) as one of successful Knowledge Engineering paradigms. The domain of hydraulic circuit design and case-based reasoning are briefly reviewed. Then a proposed methodology in automatic circuit design and dynamic learning with the use of CBR is described. Finally an app...

A nonlinear optimal control approach based on an implicit nite dimensional discrete model is presented which determines the optimal opening of a regulator gate at the upstream end in the case of a single reach hydraulic system in order to minimize the waste water and the variation of the water depth The nonlinear discrete model is obtained from the well known Preissmann nite di erence scheme Th...

The design of hydraulic control systems is a complex and time-consuming task that, at the moment, cannot be automated completely. Nevertheless, important design subtasks like simulation or control concept selection can be efficiently supported by a computer. Prerequisite for a successful support is a well-founded analysis of a hydraulic system’s structure. The paper in hand contributes right he...

The positioning of isolation valves on water distribution networks is a hard design issue in hydroinformatics. Hydraulic engineers usually solve it by way of genetic algorithms, which do not exploit the constrained structure of the problem. Several solving approaches, based on constrained optimisation, have been developed in Artificial Intelligence, and prove that this discipline can surely hav...

Nearly all tractor PTO arrangements used today consist of a rotating mechanical shaft with two or more universal joints. This arrangement continues to be an entanglement hazard. By driving the attachment with fluid power, this hazard could be eliminated. This project included the design, development, and testing of an experimental tractor based on a John Deere 4040. The entire power train was t...

The Hydraulic External Pre-Isolator (HEPI) is the first 6 degrees of freedom active seismic isolation system implemented at the Laser Interferometer Gravitational Wave Observatory (LIGO). Implementation was first completed at the LIGO Livingston Observatory (LLO) prior to LIGO’s 5th science run, successfully cutting down the disturbance seen by LLO’s suspended optics in the two most prominent s...

This paper describes the scientific principles of Darcy’s law and hydraulic resistance as they relate to the in-ground dispersal of onsite wastewater effluent. A clear understanding of how water moves into the ground via dispersal trenches is needed to facilitate proper system design and effect some standardization of dispersal trench sizing and design. Hydraulic conductivity of the media, hydr...
