Data‐Driven Adaptive Observer for Fault Diagnosis [PDF]
Mathematical Problems in Engineering, 2012 This paper presents an approach for data‐driven design of fault diagnosis system. The proposed fault diagnosis scheme consists of an adaptive residual generator and a bank of isolation observers, whose parameters are directly identified from the process data without identification of complete process model. To deal with normal variations in the process,

Observing conflicting actions elicits conflict adaptation.
Journal of Experimental Psychology: General, 2020 A key prediction of ideomotor theories is that action perception relies on the same mechanisms as action planning. While this prediction has received support from studies investigating action perception in one-on-one situations, situations with multiple actors pose a challenge because in order to co-represent multiple observed actions, observers have ...

Output feedback sliding mode control based on adaptive sliding mode disturbance observer
Measurement + Control, 2022 In this paper, an adaptive sliding mode disturbance observer is designed to counteract the disturbance actively. By designing the adaptive laws, the assumptions on the disturbance are relaxed in the proposed observer, its first derivative upper bound is ...
