This paper proposes a control strategy for a cable‐suspended robot based on an optimal sliding mode approach confronted by external disturbances and parametric uncertainties. This control algorithm is based on the Lyapunov technique, which is not only able to provide the stability of the end‐effector with an acceptable precision but also provides the optimal path in...

Crosstalk and especially far-end crosstalk (FEXT) represents the most serious source of disturbance in today’s digital transmission systems. It mostly limits the information capacity of current xDSL digital subscriber lines and also of local data networks with unshielded and or shielded twisted pairs (UTP/STP). The elimination of FEXT will require the implementation of advanced methods for its ...
