Descrição

This paper describes solutions that can be applied to pneumatic manipulator problems in positioning, both for angle trajectories and for long linear trajectories, used in construction tasks. Optimal positioning of a pneumatic manipulator along angle trajectories with minimum control energy consumption is given. The implementation of the control system is presented. Control algorithms for a long linear trajectory manipulator based on two-phase and three-phase motion modes of the end-effector are investigated. Conventional and fuzzy logic controls of a pneumatic manipulator were applied and experimental testing was carried out. The obtained results allow widening the application range of pneumatic manipulators in construction, particularly in gantry type machines. http://www.sciencedirect.com/science/article/B6V20-45C1YKY-1/1/8c256d0f2511246ffa2d121580db3d4f
