Stability with nonlinearity in a sector [PDF]
IEEE Transactions on Automatic Control, 1966 Recent investigations of the stability of a class of nonlinear systems have extended the results of Popov. The block diagram representation of the problem is shown in Fig. 1 where the linear part having a transfer function G(s) (satisfying certain conditions) is followed by a nonlinear gain K(\sigma) ranging from 0 to \infty.

Nonlinear Stability at the Eckhaus Boundary [PDF]
SIAM Journal on Mathematical Analysis, 2018 The real Ginzburg-Landau equation possesses a family of spatially periodic equilibria. If the wave number of an equilibrium is strictly below the so called Eckhaus boundary the equilibrium is known to be spectrally and diffusively stable, i.e., stable w.r.t. small spatially localized perturbations.

On Stability of a Nonlinear Pendulum [PDF]
Nonlinear Oscillations, 2003 The author studies the stability of a nonlinear pendulum whose behavior is described by the Bogolyubov--Zubarev equations [\textit{N. N. Bogolyubov} and \textit{D. N. Zubarev}, Ukr. Math. J. 7, No. 1, 5--17 (1955; Zbl 0065.42703)]. By means of the direct method Lyapunov and a comparison equation of the type \[ \frac{dy}{dt} = \psi(t)[y+\sigma(t,\mu ...

Nonlinear Stability for Thermal Convection in a Brinkman Porous Material with Viscous Dissipation
Transport in Porous Media, 2020 We investigate nonlinear stability in a model for thermal convection in a saturated porous material using Brinkman theory, taking into account viscous dissipation effects.

Geophysical Research Letters, 2016 Wide compensated vortices are not able to remain circular in idealized two‐layer models unless the ocean depth is assumed to be unrealistically large. Small perturbations on both cyclonic and anticyclonic eddies grow slower if a middle layer with uniform

Nonlinear stabilization in infinite dimension
Annual Reviews in Control, 2013 Significant advances have taken place in the last few years in the development of control designs for nonlinear infinite-dimensional systems. Such systems typically take the form of nonlinear ODEs (ordinary differential equations) with delays and nonlinear PDEs (partial differential equations).
