Advanced Control Theory - 4 credits
This course describes basic concepts and techniques for the analysis and design of a number of advanced model based controllers: amongst others robust controllers (H-infinity), internal model controllers, and feedforward controllers. To limit the complexity of the maths, the course is limited to the simplest class of systems: linear single input single output systems. Moreover, the course does not put the emphasis on maths but on the hands on experience: design, implementation, and critical evaluation of the advanced controllers. Therefore the course also provides practical insight that is very useful to design and implement the controllers.
Advanced Measurement and Identification - 4 credits
Engineers and scientists build models to understand, describe, predict and control the behaviour of the environment. In order to create these models it is necessary to combine the mathematical models with (noisy) measurements.
In this advanced course, we will explore the consequences of having systems which do not satisfy the basic assumptions made when making frequency response function measurements. That is, we will learn how to deal with nonlinearities and time variations.
Also, an introduction is given to the measurement of very high frequency signals and systems, and to the use of recursive identification techniques. In addition to a sound theoretical basis, we will also provide the students with hand on experiences in the labs.
CAE-tools for the Design of Analog Electronic Circuits - 4 credits
Analysis and design of analog electronic circuits is done using computer aided engineering (CAE) tools. The methods used comprise dc analysis, ac analysis, transient analysis, harmonic balance analysis, shooting method, large-signal / small signal analysis,… It is evident that every tool is optimized to analyze a specific type of circuit or analysis. Take for example the transient simulation which is available in SPICE. This transient simulator is not suited for analyzing nonlinear microwave circuits or for the noise analysis in mixers. To solve this problem, simulation techniques such as harmonic balance were developed. Harmonic balance assumes that all signal are either periodic of quasi-periodic. This makes harmonic balance unsuited for non-quasi-periodic signals, but makes the technique superior for the analysis of nonlinear microwave circuit and the noise analysis of mixer.
The aim of the course is to teach the future engineer the pros and contras of the different available simulation tools. This way, he/she should be able to judge which CAE-tool is the most appropriate for solving his/her design or analysis problem. Besides the choice of the analysis tool, there is also the problem of setting the simulation parameters correctly. This requires some background in the actual implementation of the simulations techniques. Hence, a theoretical background of the different simulation techniques must be given in the course. In addition to the theoretical aspect, it is important to have practical experience with the simulation tools. This will lead to a future engineer which does not lose time by simulating with a sub-optimal simulation tool.

Identification of Dynamical Systems - 4 credits
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.
