ABSTRACT
This chapter presents the use of numerical simulation and experimental identification of the electrohydraulic position servomechanisms with laser feedback set up on mobile equipments that are used for improving the quality of the lands in hydropower dams, agricultural lands, civil engineering works, and so on. The match of the numerical simulation and the laboratory validation are very useful tools for the preliminary tuning of any leveling system before setting up on any leveling machine. The specific tuning of servosystems needs three different activities. These include: numerical simulation of a servomechanism with laser position feedback, experimental identification of the operating parameters of a real complete system, and laboratory identification activities on a device that reproduces the operation conditions of the electrohydraulic servomechanism mounted on a typical leveling equipment. The modular mechatronic system with laser, electronic, and electrohydraulic components that allows reaching the leveling technology may be mounted on any land-leveling equipment whose work bodies, scoops, or blades are hydraulically powered.
