Anti-lock braking system (ABS) is considered an essential safety in electric vehicles that works to grant a reliable vehicle driving experience, and it very important ensure the security of such onboard system. This work presents detailed analysis associated with comparison includes several techniques based on pattern recognition for biasing fault detection wheel speed sensors. These are K-near...

The problem of changes detection in dynamical properties of signals and systems appears in many problems of signal processing, navigation and control (Basseville & Benveniste, 1986; Benveniste et al., 1987; Gadzhiev, 1992; Chen & Patton, 1999; Chan et al., 1999; Hajiyev & Caliskan, 2003; Vaswani, 2004; Tykierko, 2008; Li & Jaimoukha, 2009). Abnormal measurements, sudden shifts appearing in the ...

Making manufacturing systems more robust i.e. able to carry out their function under the presence of faults, is an issue of paramount importance. This issue involves on-line real-time detection of faults, diagnosis of faults, and recovery from the faults. In this paper we present a methodology that is able to generate practical and efficient solutions to this problem. Our methodology is availab...

Induction motors plays the most important role in any industry. Induction motor faults results in motor failure causing breakdown and great loss of production due to shutdown of industry and also increases the running cost of machine with reduction in efficiency. This needs for early detection of fault with diagnosis of its root cause. In this research paper a wavelet based fault classification...

This paper deals with the Robust Fault Detection (RFD) problem for multilinear affine uncertain systems and proposes an approach to solve it. Convex Minkowski combinations are used to compute as precisely as possible uncertainty sets according to the parameters variations in a fault-free context. Faults to be detected are characterized either by a parameter change outside its definition interva...
