General goal of the course 

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.

A selection of advanced data-driven modelling and estimation techniques is discussed. At the end of the course, the students should be able to select the appropriate tool for each problem, understand the influence of the tuneable parameters, and implement them on simple practical problems.

Also, an introduction is given to the measurement of very high frequency signals and systems. In addition to a sound theoretical basis, we will also provide the students with hands-on experiences in the labs.

Short outline

  • High-frequency Measurements When working with systems that operate at very high-frequencies (~ GHz, e.g. telecom applications), conventional sampling approaches are inadequate to process the data. Mixed analog-digital techniques, in combination with frequency conversions and sub-sampling will be discussed to circumvent this problem.
  • Recursive identification with exponential forgetting factor. This technique allows to perform parametric identification in real-time, as measurement data becomes available gradually.
  • Kalman filtering is a recursive technique, which allows to track the states of systems, based on observations. This is very often used in e.g. navigation. A link between physics based modelling and state-space models will be developed.
  • Gaussian process regression is a Bayesian approach to fit a model to the data. It is often used in machine learning applications, and has the advantage of conveniently mitigating the problem of model complexity selection. This approach will also be applied to obtain improved estimates of FRFs of LTI systems.
  • Measurement and data-driven modelling of LTV systems Although the Linear Time Invariant (LTI) framework is very convenient, it only allows for approximate descriptions of the reality. In this part, we will discuss the tools to detect, quantify and describe the time-varying behaviour of systems. These include the non-parametric estimation Time-varying transfer functions and the parametric estimation of differential equations with time-varying coefficients.

Algemene competenties

To successfully complete the course, you are expected to master theoretic concepts. 

  • Understand the derivation of the discussed recursive algorithms, and the influence of the associated tuneable parameters
  • Understand the concepts of Bayesian estimators, including the formulation of the prior knowledge and the a posteriori estimate in the case of a Gaussian prior.
  • Understand the formulation of prior knowledge, specific for the gaussian process regression of transfer functions of linear time invariant systems
  • Understand and explain the appearance of time-varying behaviour in engineering applications. 
  • Understand, explain and interpret analogue (high-frequency) spectral measurements

Since for an engineer practical application of the material is crucial, you are also expected to 

  • Construct a recursive estimator for a linear regression model
  • Construct a state-space model for a given simple physical system
  • Construct a Kalman filter for a given state-space model to predict and estimate the states of a system, based on measurements.
  • Independently design and realize a spectral measurement on the hardware platform provided in the labs 
  • Apply the detection and quantification tools for time variations 
  • Implement the non-parametric estimator of the time-varying transfer function
  • Relate practical hardware settings and choices to the theoretic developed concepts 

Factors that determine the judgement 

  • You are critical with respect to your explanations and results 
  • You solve simple, practical problems that are in direct relation to the course 
  • You fluently understand the hypotheses used in the theory and can indicate their importance. 
  • You show some practical measurement experience 
  • You express yourself in a clear, structured way, both in oral and written communication
