Abstract In this paper, the global exponential synchronization in arrays of neural networks with distributed delays and coupling is investigated. Without assuming the inner coupling matrix to be diagonal, by employing a new Lyapunov-Krasovskii functional, applying the theory of Kronecker product of matrices and the linear matrix inequality (LMI) technique, a sufficient conditions in LMI form is...

For T-S fuzzy systems with hard constraints and disturbances modeled by impulses, a constrained H2 control scheme in the framework of LMI (Linear Matrix Inequality) optimization is proposed in this paper. First, the H2 norm is chosen as measurement of disturbance attenuation level, and sufficient conditions for guaranteeing an H2 performance are given. Then, under the bound assumption of the di...

The localisation of a low-molecular-weight bronchial protease inhibitor (LMI) in human peripheral lung tissue was studied by an immunohistochemical method. This inhibitor was found exclusively in a part of the non-ciliated cell population of the bronchiolar epithelium. An inverse relationship was observed between the number of LMI-positive non-ciliated cells per millimetre of basement membrane ...

Sufficient linear matrix inequality LMI conditions to verify the robust stability and to design robust state feedback gains for the class of linear discrete-time systems with time-varying delay and polytopic uncertainties are presented. The conditions are obtained through parameter-dependent Lyapunov-Krasovskii functionals and use some extra variables, which yield less conservative LMI conditio...

In this paper, we propose a nonlinear state feedback controller based on linear matrix inequality (LMI) for class of systems with parametric uncertainties and external disturbances. The primary goals the proposed are to guarantee system stability performance in presence time-dependent To meet specified objectives, LMI form is calculated as hierarchical control structure. Using Lyapunov function...

In this paper, we propose a new LMI-based method for robust state-feedback controller synthesis of discrete-time linear periodic/time-invariant systems subject to polytopic uncertainties. In stark contrast with existing approaches that are confined to static controller synthesis, we explore dynamic controller synthesis and reveal a particular periodically timevarying dynamical controller struct...

background and aims. microleakage is still one of the major problems of composite-based restorations. this study compared the microleakage and thickness of resin cement in ceramic inlays with various temperatures. materials and methods. class v cavities were prepared on the buccal and lingual aspects of thirty human molars with occlusal margins in enamel and gingival margins in dentin (3 mm wid...

In this paper, we consider the problems of stability analysis and control synthesis for first-order hyperbolic linear Partial Differential Equations (PDEs) over a bounded interval with spatially varying coefficients. We propose Linear Matrix Inequalities (LMI) conditions for the stability and for the design of boundary and distributed control for the system. These conditions involve an infinite...
