Compared with conventional wireless sensor networks (WSNs), industrial WSNs (IWSNs) have stricter requirements in real-time data transmission, energy consumption, and uniformity. To fulfill these requirements, a new energy-efficient clustering approach using quantum-related bioinspired optimization, i.e., quantum elite gray wolf optimization (QEGWO), is proposed to improve the performance of IWSNs. Innovatively, operator, including probability amplitude, rotation gate, NOT designed QEGWO...

Abstract The work revisits the topic of filtering for discrete‐time singular nonhomogeneous Markovian jump systems (DSNMJSs) with time‐varying delays. An updated Lyapunov–Krasovskii functional (LKF) that has been discretely state‐decomposed is presented. This proposed LKF used to derive some delay‐ and mode‐dependent sufficient conditions DSNMJSs. On this basis, a error system causal regular via applying filter developed. A novel discrete state decomposition‐reorganization technology then...

Abstract This research focuses on the stability of discrete‐time Markovian jump neural networks with time‐varying delays. To this aim, a nonorthogonal free‐matrix‐based summation inequality (NFMSI) is proposed by constructing polynomials auxiliary scalars as well vectors. The NFMSI can avoid delays in denominator and prevent loss some coupling information compared to exiting inequalities. Then, an ameliorative criterion derived utilizing other estimation method. Finally, advantage obtained...

Abstract In this paper, a robust H ∞ control problem is considered for an uncertain singular system. An active disturbance rejection method called equivalent input (EID) used to reduce the influence of exogenous disturbances and uncertainties on At first, there exists EID, which can produces same effect system as do in channel according EID concept.

This paper investigates the problem of delay-dependent stability analysis for systems with interval time-varying delay. By means a new double free-matrix-based integral inequality and augmented Lyapunov–Krasovskii functionals containing as much information delay possible, criterion is established. Firstly, by term two-step estimation approach combined single inequalities, criteria presented. Then, compared approach, proposed more related time delays has potential to lead less conservatism....

In this paper we first extend a generalization of Ostrowski type inequality on time scales for functions whose derivatives are bounded and then unify corresponding continuous discrete versions. We also point out some particular integral inequalities as special cases.

Abstract The issue of the reliable exponential H ∞ filtering (HF) is revisited for singular Markovian jump time‐delay systems (SMJTSs) accompanied by sensor failures and interval time‐varying delays. By a new mode‐dependent Lyapunov–Krasovskii functional (LKF) containing three augmented nonintegral terms, some mean‐square exponentially admissible (MSEA) conditions satisfying an performance are derived subject to state decomposition method. On this basis, novel filter design approach first...

In this paper, a multigrid algorithm is presented for the mortar element method Morley nonconforming plate element. Based on theory developed by Bramble, Pasciak, and Xu in [Math. Comp., 56 (1991), pp. 1--34], we prove that W-cycle optimal, i.e., convergence rate independent of mesh size level. Moreover, variable V-cycle preconditioner constructed, which results preconditioned system with uniformly bounded condition number.
