Determining the domain of attraction of hybrid non-linear systems using maximal Lyapunov functions. (English) Zbl 1194.34018

Summary: A method is presented to find systematically the domain of attraction (DOA) of hybrid non-linear systems. It has already been shown that there exists a sequence of special kind of Lyapunov functions V n in a rational functional form approximating a maximal Lyapunov function V M that can be used to find an estimation for the DOA. Based on this idea, an improved method has been developed and implemented in a Mathematica-package to find such Lyapunov functions V n for a class of hybrid (piecewise non-linear) systems, where the dynamics is continuous on the boundary of the different regimes in the state space.

In addition, a computationally feasible method is proposed to estimate the DOA using a maximal fitting hypersphere.
