Algebraic analysis on asymptotic stability of continuous dynamical systems

Published: 08 June 2011 Publication History

Abstract

In this paper we propose a mechanisable technique for asymptotic stability analysis of continuous dynamical systems. We start from linearizing a continuous dynamical system, solving the Lyapunov matrix equation and then check whether the solution is positive definite. For the cases that the Jacobian matrix is not a Hurwitz matrix, we first derive an algebraizable sufficient condition for the existence of a Lyapunov function in quadratic form without linearization. Then, we apply a real root classification based method step by step to formulate this derived condition as a semi-algebraic set such that the semi-algebraic set only involves the coefficients of the pre-assumed quadratic form. Finally, we compute a sample point in the resulting semi-algebraic set for the coefficients resulting in a Lyapunov function. In this way, we avoid the use of generic quantifier elimination techniques for efficient computation. We prototypically implemented our algorithm based on DISCOVERER. The experimental results and comparisons demonstrate the feasibility and promise of our approach.
