In collaboration with industrial partners the KfK has developed such Extended Multi joInt Robot (EMIR) which is driven by hydraulic actuators. The position control of EMIR is a tough problem due to the extreme nonlinearities of the kinematics and hydraulic actuators as well as the remarkable elasticities of the mechanics and hydraulics. In the first part of this paper a realistic physically transparent model of the robot will be presented. In the second part different suitable control concepts based on the model will be discussed.enautomatic controlhydraulic large range robotmodel-based control conceptsmodelling of nonlinearities and elasticity004629journal article
