The problem of partial unknown input (UI) reconstruction is addressed. It is considered that a linear functional of the UI vector has to be reconstructed using output information only. Necessary and sufficient conditions are given allowing for the reconstruction in finite time of the required UI’s; analogous conditions are obtained for the asymptotic reconstruction of the required UI’s. The sol...

For a sensor fault diagnostic system of aircraft engines, the health performance degradation is an inevitable interference that cannot be neglected. To address this issue, this paper investigates an integrated on-line sensor fault diagnostic scheme for a commercial aircraft engine based on a sliding mode observer (SMO). In this approach, one sliding mode observer is designed for engine health p...

UNLABELLED Fault Tolerant Contact Map Reconstruction (FT-COMAR) is a heuristic algorithm for the reconstruction of the protein three-dimensional structure from (possibly) incomplete (i.e. containing unknown entries) and noisy contact maps. FT-COMAR runs within minutes, allowing its application to a large-scale number of predictions. AVAILABILITY http://bioinformatics.cs.unibo.it/FT-COMAR

This paper describes a method for designing sliding mode observers for detection and reconstruction of faults, that is robust against system uncertainty. The method uses H∞ concepts to design the observer, minimising the effect of the uncertainty on the reconstruction of the faults. A VTOL aircraft example taken from the fault detection literature is used to demonstrate the method and its effec...

The method of breakpoint-match-tracing is a new numerical simulation one to reconstruct the fault deformation process in three-dimensional space. This method, however, based on the spatial data relationship of three dimensional geological bodies, will reconstruct their original relationship result from using match path to trace the breakpoint and computation. Through picking up the breakpoint i...

A new method for the design of robust fault reconstruction filters is introduced in this paper. The method is based on shaping the map from disturbance inputs to the fault estimation error through frequency weighting functions and formulating the problem as a robust observer design where the input-output error map is minimized by solving a set of matrix inequalities. A numerical example consist...
