a new type-ii fuzzy logic based controller for non-linear dynamical systems with application to 3-psp parallel robot
abstract type-ii fuzzy logic has shown its superiority over traditional fuzzy logic when dealing with uncertainty. type-ii fuzzy logic controllers are however newer and more promising approaches that have been recently applied to various fields due to their significant contribution especially when the noise (as an important instance of uncertainty) emerges. during the design of type- i fuz...
15 صفحه اولDesign and Analysis of a Spatial 3-DOF Parallel Manipulator with 2T1R-Type
A novel asymmetrical spatial parallel manipulator with three degrees of freedom is proposed. The moving platform of the manipulator has two‐translational and one‐rotational (2T1R) DOFs with respect to the fixed base. Two other manipulators with platforms with high rotational ability are obtained by making simple changes to the original manipulator’s architecture. The platform o...
متن کاملControl of a 3-dof Over-actuated Parallel Mechanism
This paper presents the control of ARCHI, a 3-dof over-actuated parallel mechanism, designed as a subpart of a 5-axis hybrid machining robot. Control strategies of the parallel sub-mechanism (3 dof / 4 actuators) managing the internal constraint on the mechanism are proposed and experimental results are discussed.
متن کاملType synthesis of 3-DOF linear translational parallel manipulators
Three-DOF linear TPMs (translational parallel manipulators) refer to TPMs whose forward displacement analysis can be performed by solving a set of linear equations. Based on the results of the type synthesis of TPMs, the method for the type synthesis of linear TPMs composed of R (revolute) and P (prismatic) joints and the displacement group theory, this paper deals with the type synthesis of li...
