Diagnosis of intermittent faults in Multi-Agent Systems: An SFL approach

Distributed Fault Diagnosis via Iterative Learning for Partial Differential Multi-Agent Systems with Actuators

“…The mathematical symbols and lemmas in the Preliminaries lay the foundation for subsequent analysis and description. Based on references [13][14][15][16][17][36][37][38][39], the dynamic model is constructed in the problem statement, addressing the fault diagnosis problem for a class of partial differential MASs. Furthermore, appropriate ILC protocols are designed to diagnose faults within the MAS.…”

“…Suppose that faults should be promptly diagnosed and addressed after occurrence, the distributed nature of MASs makes faults prone to propagating among their networks, leading to MAS paralysis and causing severe economic losses [12]. Consequently, considering the reliability and security of MASs in real-world scenarios, issues related to fault diagnosis have garnered widespread attention [13][14][15][16][17]. For instance, in [13], a sliding mode observer addressed the fault detection issue in MASs subject to disturbances.…”

“…In contrast, the scheme relied on estimating both the self-state and the neighboring states. Additional research reports on fault diagnosis in MASs can be found in references [16,17].…”

“…Thus, the objective of diagnosing system faults can be achieved by iteratively adjusting the introduced virtual faults through the residual signal using ILC methods. Unfortunately, as evident from the mentioned references [13][14][15][16][17][26][27][28], these studies primarily address fault diagnosis issues in the time domain for MASs.…”

“…(1) Unlike the fault diagnosis for ordinary differential MASs discussed in [13][14][15][16][17] The remaining sections of the article are organized as follows: In Section 2, fundamental knowledge will be provided, problem will be formulated under certain assumptions, and a description of the MASs is presented. Section 3 will focus on the design of a suitable fault estimator and ILC protocol.…”
