Model Based Fault Diagnosis and Supervision of Machines and Drives
TL;DR: In this paper, the authors describe a general methodology for the fault diagnosis of machines and drives by using few sensors, dynamic process and signal models and parameter estimation, which are then fed into a knowledge based fault diagnosis component.
Error Recovery in Automation - An Overview
TL;DR: This paper attempts to provide an overview of techniques and approaches to error recovery, both in automation and in other fields (such as autonomous robotics) where analogous problems occur.

An actuator fault isolation strategy for linear and nonlinear systems
Weitian Chen,Mehrdad Saif +1 more
TL;DR: In this article, the authors considered constant actuator faults, that is, the outputs of some actuators are stuck at fixed undesirable constant values, and proposed a fault isolation strategy based on combining the conventional observer design techniques with adaptation techniques.

Fault detection and isolation for PEM fuel cell stack with independent RBF model
TL;DR: It was found that the residual is sensitive to the fault when a static neural network model is used in system fault detection, and the use of a radial basis function network in independent mode as the system model for fault detection was proposed.
Journal ArticleDOI
Adaptive Filtering for Robust Proprioceptive Robot Impact Detection Under Model Uncertainties
TL;DR: In this paper, a new adaptive residual evaluation method is proposed to detect external impacts applied to the robot using proprioceptive information with maximal sensitivity, which is based on the difference between the estimated and the actual applied torques.

Paper: A survey of design methods for failure detection in dynamic systems
TL;DR: This paper surveys a number of methods for the detection of abrupt changes in stochastic dynamical systems, focusing on the class of linear systems, but the basic concepts carry over to other classes of systems.

Parameter estimation for continuous-time models-A survey
TL;DR: The paper reviews the progress of research on parameter estimation for continuous-time models of dynamic systems over the period 1958-1980 and includes a classification system which conforms as closely as possible to that which has arisen naturally over the past two decades.
