Linearization and Robust Control of Scara Robot used in manufacturing

This paper presents a new linearization technique to be used for robust control of an SCARA robot manipulator. Some nonlinear terms in the model of robot manipulator are compensated by linear terms which are introduced in the paper. Linearization process is carried out for four arms but QFT is only applied to design feedback controller for the first arm. The research indicates that applying the proposed technique successfully overcomes obstacles for robust control of nonlinear SCARA robot.
