Zonotopic fault detection for 2-D FMLSS systems with adaptively event-triggered mechanism

This paper studies zonotopic fault detection (FD) for two-dimensional (2-D) FMLSS systems with adaptively event-triggered mechanism. The exogenous disturbance and measurement noise are assumed to be unknown-but-bounded (UBB) for the 2-D systems. The adaptively event-triggered mechanism is utilized for the first time in 2-D FMLSS systems to save limited communication resource. The generated residual signal is robust against external disturbance and measurement noise, and sensitive to fault by designing a L<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">∞</inf>/H<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">∞</inf> fault detection observer (FDO). Subsequently, based on the obtained FDO, a zonotopic residual evaluation scheme is framed subjected to the impacts of event-triggered scheme, noise and disturbance. Finally, a numerical example is provided to certify the validity of the proposed adaptively event-triggered based on zonotopic fault detection method.
