Fault Detection in a Heat Exchanger, Comparative Analysis between Dynamic Principal Component Analysis and Diagnostic Observers
(Revista Computación y Sistemas; Vol. 14 No. 3, 2011-03-08)
Abstract. A comparison between the Dynamic Principal Component Analysis (DPCA) method and a set of Diagnostic Observers (DO) under the same experimental data from a shell and tube industrial heat exchanger is presented. ...
Actuator fault tolerant control based on probabilistic ultimate bounds
(Elsevier Science Inc., 2019-01)
In this work we introduce a novel set-based fault tolerant control scheme for linear systems under Gaussian disturbances. In the proposed strategy, actuator faults are detected and diagnosed when residual trajectories enter ...
