Christian Döschner

from Wikipedia, the free encyclopedia

Christian Döschner (born September 25, 1936 in Mylau ) is a German engineer and professor for process analysis and control engineering modeling . He is one of the pioneers of automation technology in this field and is a co-founder of the training of qualified engineers in the field of control technology / automation technology.

Career

Christian Döschner was born in Mylau in the Vogtland in Saxony . After finishing school, he learned the trade of a locksmith. Then he attended a high school, which he graduated from high school.

In 1956 he began studying at the Technical University of Dresden , Faculty of Mechanical Engineering, specializing in precision mechanics / control engineering at the Institute for Control Engineering, newly founded in 1955 (Director: Heinrich Kindler ). This institute was the first of its kind in the German-speaking area, and Döschner belonged to the early generation of students at this institute, which included the later automation professors Hans-Joachim Zander and Horst Strobel (Dresden), Wolfgang Weller (Berlin) and Heinz Töpfer (Magdeburg / Dresden ) emerged. It was here in 1962 that Döschner acquired his first academic degree, Diplom-Ingenieur (Dipl.-Ing.) Specializing in control engineering .

Scientists in Magdeburg

After graduating, Döschner began his professional activity in 1962 at the Technical University "Otto von Guericke" Magdeburg (THM), Faculty of Mathematics, Natural Sciences and Basic Technical Sciences as a scientific assistant at the Institute for Technical Mechanics (Director: Heinrich Wilhelmi ). However, he soon switched to the Institute for Control Engineering, which Heinrich Wilhelmi had founded in 1960, and since 1963 the Institute for Measurement, Control and Regulation Engineering . Döschner was thus one of the first assistants at this facility together with Herbert Ehrlich , and he played a key role in building up the control engineering training in Magdeburg and shaped modeling as a special part of their profile.

Here he began his research on control engineering modeling for distillation columns . As early as 1964, the then students Werner Kriesel with his large document and Wolfgang Wilhelmi with his diploma thesis were included. These continuously ongoing research in 1968 his is thesis emerged, with whom he for Doctor of Engineering (Dr.-Ing.) PhD was. The field of modeling for technological objects as the basis for the draft regulation was worked on by Döschner during his entire scientific activity.

Since in the course of the Third University Reform in the GDR from 1968 founded "section Technical Cybernetics and Electrical Engineering" (TK / ET; founding director: Heinz pottery ) located Döschner hired as senior assistant of an additional enhanced in structure and content design university distance education in the field of "Technical Cybernetics and Automation technology ".

At the same time, Döschner developed the research complex “Theoretical process analysis and control engineering system design”, which was interdisciplinary and extended into the 1980s in the long term. Intensive collaborations were formed with experts in process engineering and chemical apparatus and plant construction at the TU Magdeburg, with partners abroad and with industrial companies in the oil processing industry in Schwedt (Oder) and Böhlen as well as chemical plant construction in the Magdeburg region. This research cooperation was supplemented by a one-year research stay by Döschner at the Moscow Chemical-Technological Institute “Mendeleev” . Then Döschner completed his PhD B in the field of theoretical process analysis , which was converted into a habilitation in 1990 (Dr.-Ing.habil.).

In 1977 Döschner switched to the automation industry for a few years and took over the tasks of the person responsible for process computing technology in the area of ​​system engineering in the "Equipment and Controller Works Teltow" . Here he gained extensive experience for the practical orientation of his theoretical research work.

In 1980 Döschner was appointed as a university lecturer (equivalent to C3 professor ) at Magdeburg University. In particular, he set up a new research group on the "automation of industrial furnaces". After the unexpected death of Professor Siegfried Rudert in mid-1980, Döschner took over his entire training in the field of automation technology for the mechanical engineering, technological and apparatus engineering departments at Magdeburg University. In 1988 Döschner was appointed professor for automation technology here . After German reunification , Döschner became a university professor at the Otto von Guericke University in Magdeburg in 1993 . He realigned his scientific work in research and teaching:

  • Modeling and control in fluidized bed combustion and fluidized bed drying,
  • Robotics with learning algorithms for motion sequences and the use of visual information,
  • Adaptronic Systems.

Döschner continued his work on automation technology in the Institute for Automation Technology (IFAT), which was newly created in 1990 , until he retired. From 1994 to 2001 Döschner was head of the IFAT.

He also strongly promoted the next generation of scientists. In his academic school he led numerous doctoral students to doctorate who are now working in the private sector and some of them are professors themselves, including Markus Krabbes , who for many years worked as prorector and at times as rector of the Leipzig University of Technology, Economics and Culture (HTWK) .

Memberships and honors (selection)

Döschner built up and developed the German University Association (DHV) in the state of Saxony-Anhalt and from 1990 to 1993 headed it as the state association chairman with great personal commitment. Then he was its deputy chairman.

Christian Döschner's services to training, further education (distance learning from university) and research in the field of control engineering, control engineering modeling and automation technology as well as in setting up and managing the German University Association in Saxony-Anhalt were highly appreciated. In his honor, the IFAT of the Otto von Guericke University Magdeburg organized an honorary colloquium on October 8, 2001 to mark his farewell. At the same time, his active professional life was ceremoniously ended.
