Recall that in contrast to a vector, a scalar has only a magnitude. 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. Linear stability analysis can indicate when nonlinearities can be expected to dominate the dynamics, and local finite-time Lyapunov exponents can indicate regions on an attractor where these nonlinearities will cause all uncertainties to decrease—cause trajectories to converge rather than diverge—so long as trajectories remain in those regions. Approximation of initial value problems for ordinary differential equations: one-step methods including the explicit and implicit Euler methods, the trapezium rule method, and Runge–Kutta methods. Ordinary Differential Equations Igor Yanovsky, 2005 7 2LinearSystems 2.1 Existence and Uniqueness A(t),g(t) continuous, then can solve y = A(t)y +g(t) (2.1) y(t 0)=y 0 For uniqueness, need RHS to satisfy Lipshitz condition. Hence, we can represent the … A Barrier Lyapunov Function may be symmetric or asymmetric, as illustrated in Fig. systems. Stability 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.

Thus, Lyapunov functions allow to determine the stability or instability of a system. At high supersonic and hypersonic speeds there occurs new opportunities of application of non-traditional aerodynamic shapes, based on waverider and Busemann biplane conceptions (Figs. In mathematics, the Lyapunov exponent or Lyapunov characteristic exponent of a dynamical system is a quantity that characterizes the rate of separation of infinitesimally close trajectories.Quantitatively, two trajectories in phase space with initial separation vector diverge (provided that the divergence can be treated within the linearized approximation) at a rate … where f 0, f b, g 0, and g a are given functions. This paper considers the Modified Autonomous Van der Pol–Duffing equation subjected to dynamic state feedback, which can well characterize the dynamic behaviors of the nonlinear dynamical systems.
