Robust Simulation of Continuous-Time Systems with Rational Dynamics

Résumé

This paper concerns the simulation of a class of nonlinear continuous-time systems under a set of initial conditions described by an ellipsoid. By getting inspiration from Lyapunov theory, we show that it is possible to derive a procedure allowing the computation of a bounding ellipsoidal envelope which will enclose all the states that can be reached from the set of initial conditions. This numerical procedure is based on convex optimisation, and it makes it possible to set a guaranteed hard bound on the evolution of the state of the system for all the possible initial conditions. At the end of the paper, we show an application of the method through an academic example.
