Descriptor System Tools (DSTOOLS) User's Guide
Provides a practical tool for researchers and engineers working with descriptor systems, but it is a software documentation rather than a novel research contribution.
This paper presents DSTOOLS, a MATLAB toolbox for manipulating rational transfer function matrices via descriptor system realizations, providing a user's guide with examples. No experimental results are reported.
The Descriptor System Tools (DSTOOLS) is a collection of MATLAB functions for the operation on and manipulation of rational transfer function matrices via their descriptor system realizations. The DSTOOLS collection relies on the Control System Toolbox and several mex-functions based on the Systems and Control Library SLICOT. Many of the implemented functions are based on the computational procedures described in Chapter 10 of the book: "A. Varga, Solving Fault Diagnosis Problems - Linear Synthesis Techniques, Springer, 2017". This document is the User's Guide for the version V0.71 of DSTOOLS. First, we present the mathematical background on rational matrices and descriptor systems. Then, we give in-depth information on the command syntax of the main computational functions. Several examples illustrate the use of the main functions of DSTOOLS.
