Aanbieding 2 met studiegidsnummer 9017085ENR voor alle studenten in het 2e semester met een verdiepend master niveau.
Content
This course describes the various steps one has to go through for obtaining a linear dynamic model of a process. It starts with the choice (design) of the measurement setup, the choice (design) of the excitation signal, the choice of the parametric model (discrete time, continuous time, parametric versus non-parametric noise model...), the estimation of the parametric model (identification toolboxes in Matlab), till finally the model selection and the model validation. Hereby the influence of each error source (stochastic measurement errors, systematic measurement errors, non-linear distortions, time-variant effects, model errors...) on the final result is studied in detail.
Each step is illustrated thoroughly by means of real life examples.
The course starts with the basic techniques necessary to predict the stochastic behaviour of an estimator (consistency, bias, efficiency, probability density function, robustness). Furthermore, the continuous thread throughout the entire course is the formulation of the maximum likelihood solution starting from the measured data. This approach has the advantage that provides the estimated model with an estimate of its uncertainty.

This course describes the various steps one has to go through for obtaining a linear dynamic model of a process. It starts with the choice (design) of the measurement setup, the choice (design) of the excitation signal, the choice of the parametric model (discrete time, continuous time, parametric versus non-parametric noise model...), the estimation of the parametric model (identification toolboxes in Matlab), till finally the model selection and the model validation.

Each step is illustrated thoroughly by means of real life examples.
FINAL REQUIREMENTS
- Knowledge and insight: being able to analyse existing estimators and understand their stochastic behaviour; being able to design an identification experiment; being able to construct an estimator for a given identification problem.
- Opinion formation: for all topics mentioned above being able to solve simple exercises and to make choices; understanding the pros and cons of the choices made; critical attitude w.r.t. to the results obtained.
- Learning skills: using the existing identification literature, being able to solve a practical identification problem (experiment design, choice model, choice estimator, model validation, and uncertainty calculation).
- Communication: clear and accurate oral and written reporting
