About ELEC

"ELEC" stands for "Fundamental Electricity and Instrumentation" (in dutch: "Algemene Elektriciteit en Instrumentatie") and the name corresponds with the educational and research tasks and objectives of the department. The main research activity of the department is the development of new measurement techniques using advanced signal processing methods, embedded in an identification framework. 

Our research topics

The long term objective of the department is the realization of the IMMI project (Interpretation by Measuring, Modelling and Identification), since 1989. Besides this main project, which covers a broad spectrum of several related activities, also some other independent research topics (national or European funding) are at stake.

Nonparametric Time-Varying Operational Modal Analysis

The first subproject deals with the time variations of (vibrational) mechanical structures described by the nonparametric Operational Modal Analysis (OMA) [1]. OMA is a special identification technique for estimating the modal properties (e.g. resonance frequencies, damping) of structures based...

Measuring nonlinear distortions: from test case to an F-16 Fighter

What are the similarities and differences between the behavior of a small vibrating test system and an F-16 fighter? To find it out, we compare measurements of the test system to measurements from the bolted connection of the wing and the missile of a F-16 Fighter Falcon from the Belgian air...

Using the Best Linear Approximation in circuit design

The need for faster and more efficient electronic circuits pushes the devices more and more into their non-linear operating regions. The amount of non-linear distortion generated by a circuit becomes an increasingly important part of the circuit’s specifications. Most of the designers of analog...
