By using the concept of on-line goal adaptation, we develop a new paradigm of performance shaping in MRAC. The general idea is to replace the single reference model generated trajectory in classical adaptive designwith a tube referencemodel. Two alternative adaptive control schemes that lead to tractable design formulations are developed in which the performance is adapted on-line to satisfy a ...

ion a process that transforms information into information whose semantic content and scope are richer/higher than the content and scope of the initial information. Discussion Other terms We do not claim that this list of terms is complete. Several other notions e.g., cross-media references, coherency between media, anaphoru, cliexis, ,redundancy, etc. are currently used. Nevertheless, an exten...

We propose a new model reference adaptive control algorithm and show that it provides the robust stability of the resulting closed-loop adaptive control system with respect to unmodeled plant uncertainties. The robustness is achieved by using a relative error signal in combination with a dead zone and a projection in the adaptive law. The extra a priori information needed to design the adaptive...

Although the competence level in pharmaceutical cold chain logistics is adequate current healthcare sector, future will be more unpredictable, disruptive, and chaotic than world of today because rapid technological changes, as well social disruption. This work introduces evaluates a new structure based on enhanced reference process model (RPM) architecture (RA) for design. The modified Delphi t...

Abb. 1 gibt einen Überblick über das Requirements Engineering Artefaktmodell in REM. Es strukturierte die zu erarbeitenden Anforderungen im Requirements Engineering (RE Artefakte) nach den inhaltlichen Schwerpunkte Business Needs, Requirements Specification und System Specification. Die Artefakte bestimmen die Inhalte zu erarbeitender Spezifikationsdokumente der fach-übergreifenden Aktivitäten ...

This paper proposes a new control technical reference model (C-TRM) using a layered architecture. Existing control architectures are focused on specific problems and do not provide for a general control communication from goal to task to execution. The upper layers of the C-TRM deal with the goal definition and validation. The lower layers address the goal to task translation and task execution...

Fast and accurate transient response is the main requirement in electric machine position control. Conventional cascade control structure has sluggish response due to the limitation of inner control loop bandwidth. In this paper, in order to decrease the Permanent Magnet Synchronous Motor (PMSM) transient response time it can be used reference model using feed-forward signals. In this structure...

This article analyses different types of reference models applicable to support the set up and (re)configuration of Virtual Enterprises (VEs). Reference models are models capturing concepts common to VEs aiming to convert the task of setting up a VE into a configuration task, and hence reducing the time needed for VE creation. The reference models are analysed through a mapping onto the Virtual...

A particularly simple Markov chain model for a reference string is described. The model, which is only slightly more complicated than the independent reference model, generates strings that have a locality property and that have a specified probability distribution of references over pages. Expressions are obtained for expected working-set size and expected working-set miss ratio. The of change...

Events are becoming more and more important for companies as an instrument of marketing communication. The management of events is an interdisciplinary task, addressed in the most diverse fields in practice and in research establishments. Because careful preliminary planning and precise execution are extremely important for events, modeling languages, such as the event-driven process chain (EPC...
