By introducing mode-dependent double event-triggering mechanisms (DETMs), the communication resources in both system–controller (S-C) channel and controller–actuator (C-A) are saved as much possible. designing a...

This paper studies the global exponential synchronization almost surely (GES a.s.) for coupled systems (CSs) with stochastic switching topology by using event-based output feedback control. It is assumed that sensor-controller channel subject to deception attacks and actuator faults may occur some modes. Novel double mode-dependent adaptive event-triggering mechanisms (ETMs) are introduced based on sampled data technique. Not only Zeno phenomenon naturally excluded, but also asynchronous...

This article proposes an asymptotic consensus control algorithm for a vehicle platoon with time-varying communication delays and external disturbances. To avoid continuously monitoring the state of vehicles utilize network resources efficiently, event-triggered (ETC) three free parameters based on periodic sampling is designed. Consider switched topology, novel method constructed to make discretized Lyapunov–Krasovskii functional (LKF) monotonically decreasing at switching instants, which...

Abstract Three‐dimensional (3D) graphene hydrogel (GH) architectures are of great interest in applications towards electronics, environmental fields, catalysis devices, and sensors. However, due to the structure constraints graphene, only macropore low specific surface areas obtained. Conjugated microporous polymers always possess a micro‐ mesopore simultaneously, but conductivity is very poor. both pore parameter important factors affecting performance capacitor. Here, we propose facile...

Natamycin (NAT) is the drug of choice for treatment fungal keratitis (FK). However, its inherent shortcomings, such as poor solubility, high dosing frequency, and long cycle, need to be urgently addressed by designing a new delivery widen clinical utility. Growing research has confirmed that clotrimazole (CLZ) plays significant role in growth inhibition. Hence, coaxial electrospray (CO-ES) technology used herein prepare nano-systems with an average hydrodynamic particle size 309-406 nm...

This brief introduces the concept of mixed semi-Markov switching, whose sojourn time consists a certain part and an uncertain part, where is determined by process. Compared with classical concerned switching process general practical since it becomes when zero. Under stability problem for switched stochastic systems all unstable modes studied. By partitioning time, criterion established, conventional restriction that multiple Lyapunov functions are not decreasing at instants relaxed. It...

This article focuses on the stability issue of switched network control systems (SNCSs) under deception attacks described by a Bernoulli process with unknown probability distribution. The false information in is but bounded and may be state dependent or independent. By means input-to-state (ISS) tool convex combination method, an improved lemma first developed for SNCSs, which facilitates derivations our results. After that, some attack-independent sufficient conditions ISS SNCSs are...

Abstract As everyone knows, strict mode‐dependent event‐triggered mechanism (MDETM) is rarely studied for switched systems due to the difficulty in settling down relationship between dwell time (DT) and triggered intervals. This problem satisfactorily solved by considering exponential stabilization via observer‐based dual MDETMs linear systems. The on sensor‐controller (S‐C) channel controller‐actuator (C‐A) are designed respectively according average (MDADT). C‐A generated based S‐C...

This paper considers the input-to-state stability (ISS) problem of nonlinear switched systems under stochastic switching governed by both transition probability and dwell time. A novel analysis framework ISS with respect to is proposed in sense Lyapunov. It shown that exhibits a positive effect on issue, uniform can be achieved even though all subsystems are non-ISS. In addition, Lyapunov results applied linear using matrix inequality method, dynamic feedback control strategy designed...

It is well known that designing mode-dependent event-triggered control (MDETC) brings challenging difficulties to theoretical analysis, especially for two-dimensional (2-D) switched systems. Therefore, 2-D Fornasini–Marchesini local state-space (FMLSS) systems, this paper designs a MDETC investigate global exponential stabilization almost surely (GES a.s.). A based on dynamic output quantization scheme designed, which not only has wide range of practicability, but also greatly saves network...
