- The Lyapunov stability is a method that was developed for analysis purposes.[1]
- The Lyapunov stability theory can be generalized as follows.[1]
- ( x ) using the Lyapunov function method.[1]
- Notice that, for small systems, the construction of the Lyapunov function can be done manually.[1]
- This may be discussed by the theory of Aleksandr Lyapunov.[2]
- The mathematical theory of stability of motion, founded by A. M. Lyapunov, considerably anticipated the time for its implementation in science and technology.[2]
- Moreover Lyapunov did not himself make application in this field, his own interest being in the stability of rotating fluid masses with astronomical application.[2]
- More recently the concept of the Lyapunov exponent (related to Lyapunov's First Method of discussing stability) has received wide interest in connection with chaos theory.[2]
- The case represented by inequality (15b) was called by Lyapunov a “critical” case.[3]
- From the preceding definitions it follows that Lyapunov stability is only meaningful for solutions of ordinary differential equations.[3]
- Lyapunov stability of a point relative to a mapping is defined as Lyapunov stability relative to the family of non-negative powers of this mapping.[4]
- (Lyapunov's theorem on stability in a first approximation); to facilitate the verification of the condition in this theorem one applies criteria for stability.[4]
- For the study of stability in critical cases, A.M. Lyapunov proposed the so-called second method for studying stability (cf.[4]
- In automatic control, the main interest of the Lyapunov approach concerns the stability analysis of nonlinear systems.[5]
- This chapter provides an introduction to the Lyapunov stability of nonlinear fractional systems.[5]
- The introduction begins with the indirect Lyapunov method, based on a local approximation around the equilibrium point, which makes it possible to test system local stability.[5]
- The variable gradient method makes it possible to build a Lyapunov function.[5]
- A Lyapunov function is a scalar function defined on the phase space, which can be used to prove the stability of an equilibrium point.[6]
- The Lyapunov function method is applied to study the stability of various differential equations and systems.[6]
- Thus, Lyapunov functions allow to determine the stability or instability of a system.[6]
- The disadvantage is that there is no general method of constructing Lyapunov functions.[6]
- The stability of the proposed controller is proven by applying Lyapunov stability theory.[7]
- We present a Lyapunov-type approach and the Lyapunov-Floquet (L-F) transformation to derive the stability conditions.[8]
- It makes use of a Lyapunov function .[8]
- For a linear system with constant coefficients, it is rather simple to find a Lyapunov function.[8]
- Equation (2.7) is called the Lyapunov equation.[8]
- (17) to remain stable only for certain values of d and it appears to be much more difficult to find Lyapunov functionals that yield stability criteria.[9]
- Therefore, we start with the Laplace transform method to find sufficient conditions for stability and try to find similar conditions with the help of a Lyapunov functional.[9]
- (17), from which we retrieve a Lyapunov functional in Section 4.5.2.[9]
