We develop a method to numerically analyse asymptotically autonomous systems of the form \dot{x} = f (t, x), where f (t, x) tends to g(x) as t → ∞. The rate of convergence is not limited to exponential, but may be polynomial, logarithmic or any other rate. For these systems, we propose a transformation of the infinite time interval to a finite, compact one, which reflects the rate of convergence of f to g. In the transformed system, the origin is an asymptotically stable equilibrium, which is exponentially stable in x-direction.Weconsider a Lyapunov function in this transformed system as a solution of a suitable linear first-order partial differential equation and approximate it using Radial Basis Functions.
