“…This results in error or residual signals between the model-estimated features and the actual process-measured features (Patan & Parisini, 2005;Isermann, 2005). The values of these errors indicate the extent of the process malfunctioning and, thus, they are used to detect and diagnose faults, by comparing them to threshold values for the errors, or using a more elaborated statistical analysis (Patton, et al, 1995;Narasimhan, et al, 2008;Caccavale, et al, 2010;Elhsoumi, et al, 2011). Amongst model-based methods, observer-based, parity spacebased and parameter estimation-based methods are the most common.…”

“…Amongst model-based methods, observer-based, parity spacebased and parameter estimation-based methods are the most common. Model-based methods show great advantages when dealing with dynamic processes, where the monitored inputs and outputs variables are fed into a processor (i.e., diagnostic observer) that represents the knowledge about the process dynamics in order to generate a fault indicator /residual (Patton, et al, 1994;Elhsoumi, et al, 2011). However, they are associated with many shortcomings that complicate their implementation (Venkatasubramanian, et al, 2003a).…”
