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 ...

Stability conditions for abstract functional differential equations in Hilbert space
Semigroup Forum, 2002 The author studies some interesting stability properties for a class of functional differential equations of the form \[ \begin{cases} u'(t)= Au(t)+ bAu(t- h)+ \int^0_{-h} a(r) Au(t+ r)\,dr,\;t> 0,\\ u(0)= \phi^0,\quad u(r)= \Phi^1(r),\quad r\in [-h,0).\end{cases} \] Here \(A\) is the infinitesimal generator of an analytic semigroup of linear operators

Existence and comparison results for operator and differential equations in abstract spaces
Journal of Mathematical Analysis and Applications, 2002 The author proves a fixed-point theorem for increasing mappings \(G:P\to P\) (\(P\) a partially ordered set), together with monotone increasing dependence of selected fixed-points with respect to \(G\). The results are applied to discontinuous implicit functional-differential equations in ordered Banach spaces.

Elastic–Plastic Modeling and Experimental Characterization of Granular Jamming Actuators
Advanced Engineering Materials, EarlyView.Granular jamming enables rapid switching between soft and rigid mechanical states. Here, a reduced‐order elastic‐perfectly‐plastic beam framework captures pressure‐dependent loading, unloading, residual deformation, and hysteresis in jammed beams, while matching three‐point bending experiments across materials and geometries. The framework links design
