Identification in the presence of nonlinear distortions

Project Details

Description

The aim of this project is to model dynamic systems in the presence of nonlinear distortions. Two possible approaches are retained:

- The best linear approximation is identified.
- A nonlinear model is built.

To solve this problem, a number of successive steps will be made.

- How big is the problem? Detection, qualification and quantification of nonlinear distortions
- Understanding of the behaviour of nonlinear distortions: what is their impact on the linear modelling framework.
- Understanding of the linear identification framework: what is the impact of nonlinear distortions on the consistency, efficiency, ...?
- Optimal measurement methods to measure the best linear approximation: is it possible to minimize the measurement time?
- Approximate nonlinear modelling: fast nonlinear identification
- identification of block schemes
- neural networks
- models with varying parameters
