Observer‐Based Adaptive Event‐Triggered Tracking Control for Fuzzy TS Systems With Premise Mismatch
International Journal of Adaptive Control and Signal Processing, EarlyView.This paper presents an adaptive logistic event‐triggered observer‐based tracking controller for Takagi‐Sugeno fuzzy systems under constrained inputs and network delays. Leveraging a hybrid LMI and Secretary Bird Optimization approach, this strategy significantly minimizes communication overhead and computational burden while ensuring optimal reference ...

Oscillation of a Differential Equation with Fractional Delay and Piecewise Constant Arguments
Computers & Mathematics with Applications, 2006 The delay differential equation \[ x'(t) + px \bigl( t - \tfrac{1}{2} \bigr) + q x([t-k]) = 0 \tag{1} \] is considered, where \(p\), \(q \in {\mathbb R}\), \(p \neq 0\), \(k\) is a nonnegative integer, and \([\cdot]\) denotes the greatest-integer function.

Advanced Engineering Materials, EarlyView.A simplified thermoplastic pultrusion model is developed to predict thermal fields in glass fiber/polyethylene terephthalate (GF/PET) composites with reduced computational cost. By combining effective material homogenization, validation against literature data, and Gaussian‐process‐based optimization, the study reveals how heating limits, pulling speed,

Oscillation Criteria of Certain Third-Order Differential Equation with Piecewise Constant Argument
Journal of Applied Mathematics, 2012 We study the oscillation and asymptotic behavior of third-order nonlinear delay differential equation with piecewise constant argument of the form (r2(t)(r1(t)x'(t))')'+p(t)x'(t)+f(t,x([t]))=0. We establish several sufficient conditions which insure that

Advanced Engineering Materials, EarlyView.An explicit constitutive reconstruction framework enables accurate tensile characterization of miniaturized additively manufactured specimens using only the grip‐to‐grip displacement measurements. Progressive validation through self‐consistency, analytical comparison, and inverse finite element method (iFEM) benchmarking demonstrates constitutive ...

Electronic Journal of Qualitative Theory of Differential Equations, 2011 We examine scalar differential equations with a general piecewise constant argument, in short DEPCAG, that is, the argument is a general step function. Criteria of existence of the oscillatory and nonoscillatory solutions of such equations are proposed ...
