System Analysis

Background

Dynamics of large-scale systems

One focus of this group are stability properties of very high-dimensional nonlinear dynamical systems. These may arise as interconnections of many lower dimensional control systems, but also in the context of iterative decoders for forward error correction codes, like turbo codes and LDPC codes.

EXIT chart analysis

EXIT charts are a tool favored in coding theory to investigate convergence and stability properties for iterative decoders. They may as well be seen as graphical representations of the input-output behavior of two one-dimensional dynamical systems.

Stability analysis of nonlinear systems

Robustness and stability (e.g., ISS, KL estimates) for continuous-time systems as well as functional difference inclusions are within the scope of this project.
