An Adaptive Friction Compensator for Global Tracking in Robot Manipulators

A novel adaptive friction compensator based on a dynamic model recently proposed in the literature is presented in this paper. The compensator ensures global position tracking when applied to an n degree of freedom robot manipulator perturbed by friction forces with only measurements of position and velocity, and all the system parameters (robot and friction model) unknown. Instrumental for the so

The State of The Research

Introduction. Information overload, special competences need in the area of information analysis, demand of business innovation, a struggle in the grant jungle are strong factors that influence the daily work flow for a researcher. Taking these aspects into consideration, we introduce a concept that we have named The State of The Research. Aim. We aim to broaden the researcher’s view in his/her re

The pragmatics of imperative and declarative pointing

Bates (1976) is the starting-point for an analysis of pointing that does not involve explicit higher-order intentions. It is claimed that declarative pointing is essentially intersubjective, while imperative pointing is based on behaviourally motivated regularities. Declarative pointing has an indicating function. Other behaviours associated with it pertain either to its preparatory and enabling c

Uncertainty reduction in integrated control: Confronting model predictions with information from on-line data

Over the past 10-15 years WWTP control system performance has improved significantly by increased usage of on-line WWTP data. It is now time to extend the intensive use of on-line data to the sewer system, where on-line data can be used within control of both sewer and WWTP. A generic methodology for exploiting on-line sewer system data - as discussed in this paper - have revealed that these data
