Fault Tolerant-Control: Solutions and Challenges

Marcin Witczak, Marcin Pazera
2016 Pomiary Automatyka Robotyka  
Unfortunately, perfect fault diagnosis, and in particular fault identification, is impossible to attain.  ...  One of the main difficulties in the current development of FTC is the fact that most works presented in the literature treat fault diagnosis and FTC problems separately.  ...  The proposed approach is based on a triple stage procedure. It starts from actuator fault estimation, then the fault is compensated with a robust controller.  ...

ROBUST FAULT DIAGNOSIS IN CATALYTIC CRACKING CONVERTER USING ARTIFICIAL NEURAL NETWORKS

Krzysztof Patan
2005 IFAC Proceedings Volumes  
The proposed approach is tested on the example of catalytic cracking converter at the nominal operations condition as well as in the case of faults.  ...  To achieve a robust fault diagnosis system, an uncertainty associated with the model is also taken into account.  ...  In general, methods to achieve and analyze robustness can be divided into two groups. The first group of methods considers robustness as a part integrated into identification process.  ...
