This repository contains an implementation of the algorithms described in the paper
C. Hespe, H. Werner, "Robust Performance Analysis for Time-Varying Multi-Agent Systems with Stochastic Packet Loss," IFAC World Congress. 2023.
It may be used to recreate and validate the figures from the paper.
To do so, run either of the two main entry points in the repository, the scripts eigenvalue_contour.m and varying_graphs.m.
Be advised that the latter of these scripts has a runtime of at least one day.
The raw data used in the figures in the paper is available in the subdirectory figures.
Both of the main entry points will run simulations of multi-agent systems with packet loss.
For that purpose, an open source library which can be found on Github is utilized.
The repository is included as a git submodule and needs to be initialized using git submodule update --init.
To run the scripts in this repository, you will need a working copy of Yalmip together with a suitable SDP solver in your Matlab path.
The code in this repository was tested in the following environment:
- Windows 10 Version 21H2
- Matlab 2021b
- Yalmip 31-March-2021
The Matlab parfor feature from the Parallel Computing Toolbox is used to speed up the calculations.
Matlab should automatically detect if that toolbox is not available and run the iterations sequentially in that case.
However, this will drastically prolong the runtime of the scripts!
You may want to reduce the number of sampling points for the figures or run the calculations for smaller networks.
