Syfte

System identification treats how to construct mathematical models of dynamical systems from measured data. The doctoral student acquires knowledge about the ideas, concepts and theory of system identification. The doctoral student develops the ability to preform system identification experiments and to perform system identification using experimental data.

Kursens undervisningsformer

Undervisningsformer: Föreläsningar, seminarier, övningar, projekt. The instruction is a mixture of lectures and seminars. Problems are assigned every week and discussed the next week following the schedule for Ljungs course at ISY in Linköping http://www.rt.isy.liu.se/student/graduate/idkurs/. A project has also to be executed preferably related to the students PhD subject. The doctoral students can collaborate in the project.
