Main themes
This class is an introduction to system identification, which consists in finding an appropriate representation of a dynamical system using appropriate measurements. It will cover some of the main parametric and nonparametric methods for identifying dynamical systems, including in closed loop. It will also cover the properties of signals and model classes that are relevant for system identification. A realistic identification project will give students the opportunity to apply and implement the techniques that they will have learned.
Aims
At the end of this learning unit, the student is able to : | |
| 1 | With respect to the L.O. framework, this class contributes to the developpement of the following learning outcomes
More precisely, by the end of the class, the student will be able to :
Transversal learning outcomes :

Content
The following topics will be covered
- Nonparametric methods: temporal analysis, frequential analysis, including Fourier and spectral analysis
- Main classes of LTI systems and their properties, including the notions of identifiability and predictors
- Certain parametric methods: linear regression, instrumental variables, prediction errors, and some statistical methods including the maximum likelihood method
- The properties of (input) signal, including the notion of information content of the signals and the level of persistence of excitation.
- The convergence of the method seen
- Identification techniques for systems controlled in closed loop
Teaching methods
- Regular lectures.
- Resolutions of simple problems under the supervison of teaching assistant in order to get familiar with new concepts.
- Problem sets to be solved in small group in order to develop a deeper understanding of the concepts.
- A complete project of system identification in realistic conditions.
Evaluation methods
- Exam at the end of the year.
- Identification of a system on the basis of real input/output data (using the Matlab System Identification Toolbox, developed by L. Ljung).
- Problem sets during the year.
