FDITOOLS is a collection of MATLAB functions for the analysis and solution of fault detection problems. The functions of this collection relies on the Control System Toolbox and the Descriptor System Tools (DSTOOLS).

The implemented functions are based on the computational procedures described in Chapters 5, 6 and 7 of the book:

Andreas Varga, "Solving Fault Diagnosis Problems, Linear Synthesis Techniques", vol. 84 of Studies in Systems, Decision and Control, Springer International Publishing, xxviii+394, 2017.

This book describes the mathematical background of solving synthesis problems of fault detection and model detection filters and gives detailed descriptions of the underlying synthesis procedures.

The current release of FDITOOLS is version V1.0.6, dated May 1, 2021.

The User's Guide of the version V1.0 of the FDITOOLS collection is provided in the file fditoolsdoc.pdf. Additionally, the M-files of the functions are self-documenting and a detailed documentation of each function can be obtained online by typing help with the corresponding M-file name.

The codes have been developed under MATLAB 2015b and have been tested with MATLAB 2016a through 2020b. To use the functions, the Control System Toolbox and the DSTOOLS collection (Version V1.0.0.3 or later) must be installed in MATLAB running under 64-bit Windows 7, 8, 8.1 or 10.
