A Polynomial-time Algorithm for Determining Quadratic Lyapunov Functions for Nonlinear Systems
Abstract
We consider nonlinear systems dx=dt = f(x(t)) where Df(x(t)) is known to lie in the convex hull of L matrices A(sub 1),..., A(sub L) Epsilon R(expn nxn). For such systems, quadratic Lyapunov functions can be determined using convex programming techniques. This paper describes an algorithm that either finds a quadratic Lyapunov function or terminates with a proof that no quadratic Lyapunov function exists. The algorithm is an interior-point method based on the theory developed by Nesterov and Nemirovsky.
