Electro-hydraulically actuated forestry manipulator: Modeling and Identification
2012 IEEE/RSJ International Conference on Intelligent Robots and Systems, 2012 We present results of modeling dynamics of a forestry manipulator, in which we consider its mechanics, as well as its hydraulic actuation system. The mathematical model of its mechanics is formulated by Euler-Lagrange equations, for which the addition of friction forces is straightforward.
