Reference excerpt

Rolf Isermann (* 20 August 1938 in Stuttgart) is a German engineer and professor of control engineering in the Department of Electrical Engineering and Information Technology at Technical University of Darmstadt.

Professional life Rolf Isermann studied mechanical engineering at Stuttgart Technical University and graduated in 1962. In 1965, he obtained his doctorate in engineering from the same university with a dissertation entitled Das regeldynamische Verhalten der Überhitzung bei Berücksichtigung der Koppelungen mit anderen Teilen eines Dampferzeugers (The control dynamic behavior of superheaters including couplings inside the steam generator). In 1968, Isermann qualified as a teaching professor (venia legendi) with a thesis Das regeldynamische Verhalten dampfbeheizter Wärmeübertrager (The control dynamic behavior of steam heated heat exchangers) at the Fakultät für Maschinenbau of University of Stuttgart. In 1971, Isermann took up a visiting professorship at Purdue University in the US State of Indiana. In 1972, he became a teaching professor and in 1974 a professor of control engineering at the University of Stuttgart. In 1977, Isermann aceppted an appointment as successor to Professor Winfried Oppelt at the Technical University of Darmstadt. From then until his retirement in 2006, he represented the field of control engineering, process automation and mechatronic systems in the Department of Electrical Engineering and Information Technology at TU Darmstadt. From 1988 to 2001, Isermann was guiding the Collaborative Research Center 241 on Integrated Mechanical Electronic Systems (Mechatronic Systems), funded by the German Research Foundation (DFG). 1998 Isermann was a vsiting professor in the Department of Mechanical Engineering at the University of California at Berkeley. Rolf Isermann retired in 2006, and was still active in research.

Scientific Contribution Isermann's scientific work is devoted to both the theoretical and practical aspects of control engineering. In theoretical research, the focus is on modeling and controlling the dynamic behavior of technical systems, applying new methods in model identification, digital control, and adaptive control, as well as in fault detection and diagnosis of technical systems. The connection to practical issues is ensured by addressing current control engineering problems relating to areas as actuators, electrical motors, refrigeration processes, motor vehicles, power plants, oil and gas pipelines, pumps, robots, dryers, combustion engines, heat pumps, heat exchangers, rolling mills and machine tools. During his scientific career, Isermann has supervised 127 doctoral theses – a number that is extremely rare in the engineering sciences. Isermann supervised the first five doctoral theses at the University of Stuttgart. This was followed by a further 122 dissertations at the Technical University of Darmstadt. 70 percent of Isermann's research work is financed by third-party funds, a third of which comes from cooperation agreements with industry. From 1977 to 2006, Isermann's laboratory attracted a total of almost 40 million euros in third-party funding.

Worked examples

Example 1 — a first encounter with Rolf Isermann

Start with the simplest possible case. Write down what Rolf Isermann claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Rolf Isermann before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Rolf Isermann ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Rolf Isermann

In research: Rolf Isermann appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Rolf Isermann in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Rolf Isermann is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1938 births, Academic staff of Technische Universität Darmstadt, Cyberneticists, so understanding it makes those chapters shorter.
In everyday life: Look for Rolf Isermann outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
