Stability analysis for nonlinear closed loop system structure
Systems Science & Control Engineering, 2020 In this paper, stability analysis is studied for the nonlinear closed loop system with a nonlinear plant and a nonlinear controller. Without the linearizing process for the nonlinear plant and the nonlinear controller, a Lipschitz continuous assumption ...

Practical Ulam-Hyers-Rassias stability for nonlinear equations [PDF]
Mathematica Bohemica, 2017 In this paper, we offer a new stability concept, practical Ulam-Hyers-Rassias stability, for nonlinear equations in Banach spaces, which consists in a restriction of Ulam-Hyers-Rassias stability to bounded subsets.

Arthritis Care &Research, EarlyView.Objective We assessed the effectiveness of PrismRA to improve clinical outcomes among patients with rheumatoid arthritis (RA) initiating treatment with a biologic or targeted synthetic disease‐modifying antirheumatic drug (b/tsDMARD). Methods PrismRA incorporated 19 gene expression features and four clinical features to assess a patient's likelihood of

Linear and weakly nonlinear multi-diffusive convection in a Navier-Stokes-Voigt fluid layer
Arab Journal of Basic and Applied SciencesThe stability of a triply diffusive Voigt fluid layer, where fluid density is influenced by three stratifying agents with different diffusivities (e.g. heat, solute, and another solute like a third agent), has been examined. The linear stability analysis

, 1990 The Lax-Wendroff Theorem presented in Chapter 12 does not say anything about whether the method converges, only that if a sequence of approximations converges then the limit is a weak solution. To guarantee convergence, we need some form of stability, just as for linear problems.

A Q‐Learning Algorithm to Solve the Two‐Player Zero‐Sum Game Problem for Nonlinear Systems
International Journal of Adaptive Control and Signal Processing, Volume 39, Issue 3, Page 566-581, March 2025.A Q‐learning algorithm to solve the two‐player zero‐sum game problem for nonlinear systems. ABSTRACT This paper deals with the two‐player zero‐sum game problem, which is a bounded L2$$ {L}_2 $$‐gain robust control problem. Finding an analytical solution to the complex Hamilton‐Jacobi‐Issacs (HJI) equation is a challenging task.

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 ...
