Stability Analysis of Nonlinear Systems via Piecewise Linear Lyapunov Functions

Back
Abstract:
In this talk, it is addressed the issue of constructing piecewise linear Lyapunov functions (PWLLF) for nonlinear systems satisfying the generalized sector condition. PWLLF is a generalization of Polytope Lyapunov Function and the generalized sector condition is a generalization of the polytopic uncertainty. The main result of this paper is to propose a fast method to solving linear programming problems (LP's) which appear repeatedly in constructing PWLLF. The method uses a special structure of LP's which appear in constructing PWLLF.
