This paper presents a novel fuzzy sliding mode approach to control Lorenz chaotic system without chattering problem. A boundary layer and a moving fuzzy surface with an algorithm to remove chattering are used in the proposed control law. Two folds present advantages of the proposed approach: 1) it has a flexibility to define the control law without cancelling useful nonlinearities; 2) the system performance...
This paper presents a novel application of sliding control in the manual gas metal arc welding process against uncertainties. The uncertainties are due to the contact tip variation to the workpiece, measurements of the arc length and electrical current, un-modeled dynamics, parametric errors and external disturbances. The set point of arc length is performed successfully by the robust control system...
A three-fingered end-effector has been designed for use in an unstructured environment. The design has three driven inputs per finger to move the tip to the desired position in order to make contact with an object. A theoretical analysis of the three-dimensional workspace of the three-fingered gripper has been used to form a Jacobian matrix based on two inputs per finger, to provide a numerical inverse...
