“…Based on the proposed results in this paper, possible subsequent research topics include the study of finite‐time FD problems with mixed time delay 46 and with randomly occurring cyber attacks 47 . To cope with the problem of limited network bandwidth, the communication protocol can be introduced to mitigate the data conflicts, such as stochastic communication protocol, 35 round‐robin protocol 48 and so on. Moreover, it is worth noting that wireless sensor network has been widely applied in environmental monitoring, intelligent transportation and other fields, 49 thus it is also valuable to study the finite‐time FD problem for nonlinear delayed system over wireless sensor network.…”

“…In the existing literature on FD, results have mostly focused on the Lyapunov stability of the dynamic systems on infinite interval. 34,35 In applications of engineering, such as missile systems, network communication systems, and so forth, the public tend to be more interested in the behavior of dynamic systems within the finite-time interval. 36 That is to say, it is significant to make systems meeting the relevant performance requirements in finite time.…”

The attention of this article is mainly paid to the finite‐time fault detection (FD) problem for nonlinear delayed system with dynamic quantization and multiple packet dropouts. The probabilistic interval time‐varying delay is addressed, which might fall into two intervals with known probability. The measurement signals are quantized by a dynamic quantizer and then transmitted over communication network, where the multiple packet dropouts might occur. The main objective of the considered problem is to design a finite‐time FD filter such that the FD system is stochastically finite‐time stable (SFTS) with guaranteed performance in the presence of probabilistic interval time‐varying delay, dynamic quantization and multiple packet dropouts. Based on Lyapunov stability theory, sufficient criteria for the presence of the desired finite‐time FD filter are presented. Afterwards, the desired filter gain matrices are given via solving certain linear matrix inequalities (LMIs). Finally, a simulation example is used to show the applicability of the obtained finite‐time FD algorithm.

“…Thus, it is of practical significance to study the communication protocols, and there have been many research results on communication protocols. At present, RR protocol (Shen et al, 2020; Zhao et al, 2020), weighted try-once-discard protocol (Zhang et al, 2020b; Zou et al, 2016), and stochastic communication protocol (Ren et al, 2021) are the most studied communication protocols. Among them, the RR protocol is a static protocol, which evenly distributes the network usage rights to all network nodes through a preset token ring.…”

This paper focuses on the mixed [Formula: see text] and passive resilient control problem for uncertain discrete-time networked control systems subject to time delays. The measurement output is considered to be quantized by the dynamic quantizer before transmission through an unreliable communication channel, where the deception attacks may occur randomly. To further reduce the communication burden, the Round-Robin (RR) protocol is adopted to schedule sensors in a predetermined transmission order. Meanwhile, a new performance index is developed to solve restriction of the same dimension of control output and the exogenous disturbance. The S-procedure combined with a two-step uncertainties elimination method is adopted to deal with the nonlinear product terms involving multiple uncertainties. Furthermore, a decoupling method is introduced for static output feedback controller design. Sufficient conditions of the resilient controller and the dynamic quantizer are provided, which can improve the robustness of resulting closed-loop system and guarantee its stochastic stability and the specified mixed [Formula: see text] and passivity performance index. Finally, an example is given to illustrate the feasibility of the theoretical results.

SummaryThis article investigates the dissipative fault detection (FD) problem for time‐delay nonlinear Markov jump systems with measurement outliers in the case of partially unknown transition probabilities. The stochastic communication protocol is utilized to save network bandwidth, where the scheduling model is described via a Markov chain. An outlier‐resistant FD filter is constructed with the help of adaptive saturation function technology. The sufficient conditions are derived to ensure that the FD system satisfies the stochastic stability and stochastic strict dissipativity. In addition, an FD filter without saturation constraint is also designed to compare with the outlier‐resistant FD filter, which verifies that the outlier‐resistant FD filter weakens the influence of measurement outliers effectively. Finally, two examples are provided to demonstrate the feasibility and effectiveness of the designed FD scheme.
