Prof. Engmann was appointed as university lecturer at the Technical University of Ilmenau in 1976 after a leading industrial activity in the field of automation plant engineering and after habilitation in 1989. From 1992 to 2002 he was head of the department of automation plants and process control engineering at the Institute of Automation and Systems Engineering.
He represented the teaching complexes "process control engineering", "automation equipment technology", "design and specification systems", "communication systems in automation engineering", "process dynamics / theoretical process analysis" and "non-linear control systems".
In the period up to 2002, research projects were carried out in various fields: Industrial projects on the use of modern control algorithms, work on specification languages as well as on the object-oriented development of automation systems and DFG-funded work on the modelling of continuous-event-discrete systems.
