The simplest kind of an orbit is a fixed point, or an equilibrium. If a mechanical system is in a stable equilibrium state then a small push will result in a localized motion, for example, small oscillations as in the case of a pendulum. In a system with damping, a stable equilibrium state is moreover asymptotically stable. On the other hand, for an unstable equilibrium, such as a ball resting on a top of a hill, certain small pushes will result in a motion with a large amplitude that … WebMar 24, 2024 · Stability Matrix. where the matrix, or its generalization to higher dimension, is called the stability matrix. Analysis of the eigenvalues (and eigenvectors) of the stability matrix characterizes the type of fixed point .

WebThe stability of this fixed point depends on the value of parameter a 12, if a 12 < 1 then λ 2 > 1, this fixed point has two stable and one unstable eigenvalue. Therefore, we have a saddle at v 2, and if a 12 > 1, then λ 2 < 1; this fixed point has three stable eigenvalues. Therefore, we have a node at this fixed point.
