Thermal stability analysis of eccentrically stiffened Sigmoid-FGM plate with metal–ceramic–metal layers based on FSDT

open access: yesCogent Engineering, 2016
This paper researches the thermal stability of eccentrically stiffened plates made of functionally graded materials (FGM) with metal–ceramic–metal layers subjected to thermal load. The equilibrium and compatibility equations for the plates are derived by

Global stability of positive standard and fractional nonlinear feedback systems [PDF]

open access: yesBulletin of the Polish Academy of Sciences: Technical Sciences, 2020
The global stability of positive continuous-time standard and fractional order nonlinear feedback systems is investigated. New sufficient conditions for the global stability of these classes of positive nonlinear systems are established.

Sharp global nonlinear stability for a fluid overlying a highly porous material

open access: yes, 2009
The stability of convection in a two-layer system in which a layer of fluid with a temperature-dependent viscosity overlies and saturates a highly porous material is studied. Owing to the difficulties associated with incorporating the nonlinear advection

Finite-time stochastic input-to-state stability and observer-based controller design for singular nonlinear systems

open access: yes, 2020
This paper investigated observer-based controller for a class of singular nonlinear systems with state and exogenous disturbance-dependent noise. A new sufficient condition for finite-time stochastic input-to-state stability (FTSISS) of stochastic ...

Optimal control of nonlinear systems: a predictive control approach [PDF]

open access: yes, 2003
A new nonlinear predictive control law for a class of multivariable nonlinear systems is presented in this paper. It is shown that the closed-loop dynamics under this nonlinear predictive controller explicitly depend on design parameters (prediction time

Thermal Convection in a Rotating Anisotropic Fluid Saturated Darcy Porous Medium

open access: yesFluids, 2017
The stability of the thermal convection in a fluid-saturated rotating anisotropic porous material is investigated. We take into account the rotation of a layer of saturated porous medium about an axis orthogonal to the planes bounding the layer.
