Incipient Fault Detection Based on Fault Extraction

2019-5-26  Process variables can be classified into three stages: normal operation, incipient fault, and significant fault stage. A two-step incipient fault detection strategy was proposed for monitoring the complex industrial process. The first step aims at the significant fault detection using the traditional multivariate statistical process monitoring methods. Then a method combining the wavelet ...

A General Purpose Adaptive Fault Detection and

In the scheme, two generalized regression neural networks (GRNNs) are utilized for fault detection, with one as an observer and the other as an adaptive threshold generator; faults are detected by comparing the residual error and the threshold. Then, time and frequency domain features are extracted from the residual error for diagnosis.

An informational approach for sensor and actuator

In this paper, a model-based fault detection and isolation (FDI) method is proposed, with the objective to ensure a fault-tolerant autonomous mobile robot navigation. The proposed solution uses an informational framework, which is able to detect and isolate both sensor and actuator faults, including the case of multiple faults occurrence. An information filter with a prediction model based on ...

State estimation and fault detection for linear

The problem of simultaneous estimation of the continuous and discrete state with additive faults in linear switched systems is addressed. Under mild structural conditions a robust estimator is designed to solve the problem. The proposed strategy includes a technique for fault detection.
