Contributions to Control Systems in the winter semester 2016/2017

 

In order to support the professional exchange in control and automation technology far beyond the borders of our university, some years ago a colloquium series with the name “Contributions to Control Systems” was brought into being at the Institute of Automatic Control. Speakers from industry and research talk about their work in relevant developments and applications in the field of automatic control.

Operation and Maintenance Lessons Learned from a Parabolic Trough Concentrated Solar Power Plant

Dr. Astrid Hublitz

System AG
SLR STE SY EN CSY
91058 Erlangen, Germany

 

Abstrakt:

In Concentrated Solar Power Plants, solar radiation is concentrated to a receiver where heat is generated. This heat subsequently generates steam to drive a conventional thermal power plant cycle, generating electricity.

This presentation explains shortly concentrated solar power generation with parabolic trough collectors and focuses on the lessons learned from the operation of a 50 MWel CSP Parabolic Trough Plant in Spain.

A Factor Graph Approach to Parameter Identification for Affine LPV Systems

Professor Philipp Rostalski

University of Lübeck
Institute for Electrical Engineering in Medicine
Lübeck, Germany

 

Abstrakt:

Factor graphs are a versatile graphical representation of factorizable functions. As a probabilistic graphical

model, they allow to visualize structured conditional independence, which can be exploited for solving inference problems by means of message passing along the nodes of the graph. In this article we present a novel factor graph formulation of the expectation maximization, called EM-based estimation technique for affine linear parameter-varying system identification. By extending the factor graph representation of the Kalman Filter/Smoother and the EM algorithm to parameter-varying matrices, a flexible tool for nonlinear system identification in the so-called linear parameter-varying, named LPV representation is obtained. Furthermore, a recursive reformulation of the algorithm suitable for tracking time-varying changes both accounted and

unaccounted for by a pre-defined LPV system description is immediate from its factor graph-based formulation.

EWITAC – Multi-domain Modelling of Wind Turbines and Control Applications

Modelling of Wind Turbines and Control Applications DLR/Zimmer

Abstrakt:

Wind energy has become a major player in today’s electricity supply. The large share of wind energy gives rise to strict rules for grid-code compliance whereas the increasing large turbines justify more complex control algorithms and the use of modern sensor equipment such as LIDAR systems. Goal of these control challenges is not only to improve the harvesting of wind energy but also to increase turbine lifetime, ease maintenance and enable a smoother integration into the overall grid.

To meet these challenges, the software library EWITAC has been developed. Based on the open standard Modelica, this library offers a starting point for the modelling of wind turbines. Its usability is demonstrated by the design of a controller for gust load alleviation based on nonlinear dynamic inversion and the simulation of low-voltage ride through, called LVRT scenarios.
