  • PhD - Doctoral Programme

  • Engineering
Subjects Dynamics and Control
Description Robust supervision, robust control, and robust observers are since years key reserach fields of the Chair SRS (Dynamics and Control) in Duisburg. Nonlinear control is one of the major issues in the last decades of development in control. Unfortunately most of the approaches are not really relevant for practical purposes, due to their strong requirements to be made etc. Solutions developed are mainly based on robustness improvement, leading to extended assumptions about modeling errors of the model usually assumed as to be known. Observers very helpful in supervision and control but obviously the same model matching problem restricts some applications.
Within this PhD thesis topic the student is free to choose arbitrary new approaches, to extend them, to develop new ones, to extend the chairs compentence in robust nonlinear approaches based on
- robust disturbance observers,
- cognitive approaches,
- model-free or intelligent PID or similiar aproaches,
- or to combine new ones with existing ones. One assumption has to be made: The developed approach MUST be applicable to (elastic) mechanical systems (modeled as nonlinear system of higher order) or hydraulic drives or both. Experiments using the existing test rigs have to show both the functionality and the robustness of the new approaches.
Beside the development of method(s) we validate our approaches using our own test equipment. For this research several DSP-equiped test rigs are available: inverse elastic pendulum, elastic crane, fully sensored 3TS, fully sensored Hardware-in-the-Loop hydraulic cylinder for force and position control.
Therefore we need students from the automation and control field and/or mathematics with clear engineering-oriented background with
i) strong theoretical background in automation and control,
ii) strong programming skills, and
iii) shown expertise in control and control applications.
If two of the three requirements are fullfilled, feel free to apply.
From the new candidate we expect that s/he is willing to become very fast an important and valuable member of our CTS (cognitive technical systems) team within the Chair.
Therefore we expect
i) a shown and strong expertise in related scientific fields to be integrated,
ii) your ability and commitment to develop and validate NEW methods and approaches, and
iii) your willingness and commitment to write scientific contributions on a world class level.

Depending on the candidate’s background this can be related to experiences defined by the following keywords (Nonlinear control, robust control, nonlinear observers, sliding mode approaches, cognitive control, disturbance rejection, H_inf design, …)
Experiences purely related to the following keywords will not be considered for this field: SISO control, Use of Matlab/Simulink, mechatronics, …., application-oriented design of control approaches, …



In case of interest please provide beside the usual application material (CV, grades, ...) material stating that you have strong English language skills (TOEFL IBT better than 95, IETLS better than 6.5) and a detailed and described interest ONLY in the described research fields. Your German language skills can be (if necessary) improved by language courses in parallel (for example at the Goethe Institute, Düsseldorf) (on your cost). For further information about the requirements see also the website of the Chair SRS: www.uni-due.de/srs/prospective.

Be aware about the time schedule of your DAAD-application:
application now or in September/October year 1 leads to the beginning of german language courses in May/June year 2 and start PhD research at the Chair SRS in October year 2.
In case of other application (government programs, national/university training programs):
You should be supported for more than 3,5 years. In case of support for less than 3,5 years, you should convince us based on existing international publications from the last five years.
The successful candidate is primarily directly related to:
Prof. Söffker (Scientific supervisor: Prof. Söffker)

Specific prerequisites:
Bachelor and Master degree in Electrical or Mechanical Engineering or Information science or Mathematics or Automation/Control (with strong interests in programming) (with clear related specification) necessary, deep interest in the field, excellent grades in related courses.

Next steps:
1. Be aware of your national DAAD application deadline (which varies between February and November each year).
2. Contact Prof. Söffker directly by E-Mail (soeffker@uni-due.de, subject: DAAD-Appl. RNL) and send copy of CV, certificates, recommendation letters as well as a first proposal (2-3 pages) about your understanding of the intended topic, your intended working schedule, the state of the art in this field as well as the deduced definition of your project. A ‘copy and paste’-strategy will disqualify you immediately.
3. Be aware about the time schedule of your application: DAAD example application in September/October year 1 leads to begin language courses in May/June year 2 and start PhD research in October year 2.
4. Joint improvement of the proposal: If the quality of the project proposal is finally fitting to the groups standard (=perfect) Prof. Söffker will invite you by writing the required acceptance letter.
5. The final decision is with the DAAD committees.

About the Chair SRS (Head: Prof. Söffker) at U DuE, Germany:
With a mix of coworkers and PhD students financed by the university or by public funding, coworkers and PhD students financed by industry projects and PhD students financed by their home countries or by DAAD scholarships the Chair has a large tradition in supervising academic trainees. The internal organization scheme will allow an improved organization of the academic work of the PhD students in guided groups. Academic qualification includes not only the PhD topic related work but also advising coworking students (Bachelor/Master level) based on individual qualification and skills etc.

Requirements - University degree on the level of a Master (e.g. of Science, of Engineering) in Mechanical Engineering, Electrical Engineering, or a mentioned specific area of an accredited institution.
- Very good written and spoken English language skills (TOEFL IBT better than 95)
- Very good communication skills
- Able to work in an open minded, very international team
- Very good mathematical background and programming skills
- Understanding of what system theory, control technique, and system dynamics means in this field. Additionally the understanding of how such systems are technically realized is required.
- Readiness to learn german initially and for continously improvement of language skills (during the whole time of PhD work)
