Description: In this work, Artificial Neural Networks are employed in a Fault Detection and Isolation scheme for robotic manipulators. Two networks are utilized: a Multilayer Perceptron is employed to reproduce the manipulator dynamical behavior, generating a residual vector that is classified by a Radial Basis Function Network, giving the fault isolation. Two methods are utilized to choose
the radial unit centers in this network. The first method,
Forward Selection, employs Subset Selection to choose
the radial units from the training patterns. The second employs the Kohonen’s Self-Organizing Map to fix the radial unit centers in more interesting positions.
Simulations employing a two link manipulator and the Puma 560 manipulator indicate that the second method gives a smaller generalization error.

Description: This paper review the effectiveness of the parity space approach
to identify faults or disturbance in a system. The most commonly
used is the observer based procedures, and redundancy relationship
method. This involves analytical mathematical analysis of
geometry and bilinear algebra. Then, technological advances which
require complex computation such as artificial intelligence and
genetic algorithm had made tremendous improvement to fault
Detection and Isolation (FDI) analysis. Dynamic Parity Space
Approach was studied for a discrete state-space model. Important
data will be extracted using this approach especially for residual
generation which is the backbones of FDI analysis. Subsequently,
at each time instant k, the generated residuals will form a matrix
that will define the fault signature. It is remarkable that this
approach is proven in this study to be effective in diagnosis and
faults isolation.

Description: This paper describes a real-time on-line process
monitoring and fault isolation approach using PCA (Principal
Component Analysis). It also presents the software
implementation architecture using an OPC (OLE for Process
Control) compliant framework, which enables a seamless
integration with the real plant and DCS. The proposed
approach and architecture are implemented to monitor a
refinery process simulation that produces cyclohexane using
benzene and hydrogen. The result shows that both sensor
faults and process faults can be detected on-line and the
dominating process variables may be isolated.-This paper describes a real-time on-line process

Description: Robust fault diagnosis of proton exchange membrane fuel cells using a Takagi-Sugeno interval observer approach(In this paper, the problem of robust fault diagnosis of proton exchange membrane (PEM)
fuel cells is addressed by introducing the Takagi-Sugeno (TS) interval observers that
consider uncertainty in a bounded context, adapting TS observers to the so-called interval
approach. Design conditions for the TS interval observer based on regional pole
placement are also introduced to guarantee the fault detection and isolation (FDI)
performance. The fault detection test is based on checking the consistency between the
measurements and the output estimations provided by the TS observers. In presence of
bounded uncertainty, this check relies on determining if all the measurements lie inside
their corresponding estimated interval bounds. When a fault is detected, the
measurements that are inconsistent with their corresponding estimations are annotated
and a fault isolation procedure is triggered.)
