Lyapunov indirect method
http://www.math.byu.edu/~grant/courses/m634/f99/lec22.pdf Various types of stability may be discussed for the solutions of differential equations or difference equations describing dynamical systems. The most important type is that concerning the stability of solutions near to a point of equilibrium. This may be discussed by the theory of Aleksandr Lyapunov. In simple terms, if the solutions that start out near an equilibrium point stay near f…

Web13 mar. 2024 · By the indirect method of Lyapunov (as we have a polynomial right-hand side of the differential equation system all conditions for linearization are fulfilled in a neighbourhood of the origin) we know that the origin of the nonlinear system is also asymptotically stable. WebLyapunov’s Direct Method Lecture 22 Math 634 10/20/99 An other tool for determining stability of solutions is Lyapunov’s direct method. While this method may actually seem rather indirect, it does work directly on the equation in question instead of on its linearization. We will consider this method for equilibrium solutions of (possibly ...

This classical result is also known as the stability theorem with respect to the first approximation or Lyapunov's indirect method for stability. The reason for this terminology is the following: Consider the non,linear equation :e (t) = g (x (t) , x (t -h)), (4) where ...
WebThis infrastructure can be used for a number of applications. The paper focuses on transient stability monitoring, identification of out of step conditions and control. We propose an approach that is based on accurate evaluation of the system energy function (Lyapunov indirect method) and extraction of stability properties from the energy function. Web31 oct. 2024 · Which led me to believe that the system was locally asymptotically stable, but when I used the indirect method of lyapunov the system linearized about the …

WebLyapunov function. In the theory of ordinary differential equations (ODEs), Lyapunov functions, named after Aleksandr Lyapunov, are scalar functions that may be used to prove the stability of an equilibrium of an ODE.
