“…There are many methods proposed in last few decades to enhance the robustness in observer based fault detection, such as perfect unknown input decoupling [1], [2], [3], [4], optimal H 2 , H ∞ schemes [5], [6], [7], [8], total measurable fault information residual [9], and projection method [10]. Fault detection schemes for switching systems [11], [12] and semiconductor manufacturing processes [13] have also been proposed.…”

This paper considers incipient sensor fault detection issue for a class of nonlinear systems with "observer unmatched" uncertainties. A particular fault detection sliding mode observer is designed for the augmented system formed by the original system and incipient sensor faults. The designed parameters are obtained using LMI and line filter techniques to guarantee that the generated residuals are robust to uncertainties and that sliding motion is not destroyed by faults. Then, three levels of novel adaptive thresholds are proposed based on the reduced order sliding mode dynamics, which effectively improve incipient sensor faults detectability. Case study of on the traction system in China Railway High-speed is presented to demonstrate the effectiveness of the proposed incipient senor faults detection schemes.

“…In [39], for the network control system with the missing amount, the considered neural network is modelled as a Markov jump system using the stop time, and the concept of the finite frequency domain random exponent is introduced to measure the sensitivity of the residual. In [40], the fault detection of switch system with servo input and sensor stuck fault is studied. The robust control problems with finite frequency domain constraints is studied in [41, 42].…”

This study is concerned with the attack detection (AD) problems in finite frequency domain for cyber-physical systems with sensor attack. The frequency domain is divided into three frequency domains of low, medium and high, multiple AD filters are designed to work simultaneously. The attack detectionAD problem is transformed into a multi-objective optimisation schemes for each finite frequency domain. Finally, the experimental results of networked motion control system are given to verify the effectiveness and superiority of proposed method.

“…In the past decades, various reliable control methodologies have been proposed to address the control problem of different systems with actuator fault, see [23][24][25][26][27][28] and the references therein. Recently, [29] addresses a fault detection problem of switched systems with servo inputs and sensor stuck faults. By designing a switching law and its associated fault detection filters, the arbitrarily small sensor stuck faults, including outage faults can be detected in finite-frequency domain.…”

a b s t r a c tThis paper investigates the output feedback control problem of a class of nonlinear systems with sensor noise and actuator degradation. Firstly, by using the descriptor observer approach, the origin system is transformed into a descriptor system. On the basis of the descriptor system, a novel Proportional Derivative (PD) observer is developed to asymptotically estimate sensor noise and system state simultaneously. Then, by designing an adaptive law to estimate the effectiveness of actuator, an adaptive observer-based controller is constructed to ensure that system state can be regulated to the origin asymptotically. Finally, the design scheme is applied to address a flexible joint robot link problem.
