Developments of a Scilab/Matlab toolbox dedicated to LTI/LPV descriptor systems for fault diagnosis
Résumé
The paper discusses the development of a MATLAB/SCILAB toolbox for systems modeled in the LTI or LPV descriptor framework. The properties of regularity, solvability, controllability and observability are presented. Full and reduced order, proportional and proportional-integral observers are included. Some of these observers consider unknown inputs. The main contribution is provide a toolbox than can be used as auxiliary in state-estimation and fault detection based observers. These observers have been considered from few papers published recently. The fault detection and isolation can be achieved by the construction of bank of observers. These banks of observers can be built by the selection of the input/output matrices or automatically by using the proposed algorithms.
