The control of electrohydraulic robot manipulator is challenging due to the dependence of system parameters on variables such as displacement and velocity, on the geometry and inertia of the links, uncertainties associated with gravity, coriolis and centrifugal forces, variations in payload handled by the manipulator, and environmental influences. To overcome these problems, an integrated mathematical model of the 3 DOF electrohydraulic robot manipulators is treated as a large-scale uncertain system models using the known parameters of the robot. Decentralized control concept is used in this study where the uncertain system is treated as large-scale system which composed of a set of interconnected uncertain subsystems.
