Approximate Reachability for Linear Systems

Ashish Tiwari

To be presented at HSCC 2003, Prague, Czech Republic, Apr 03--05 2002, © Springer-Verlag.

Abstract

We describe new techniques to construct, and subsequently refine, over-approximations of the reachability sets for linear dynamical systems. Our approach extracts information from eigenvectors to generate invariants of the system. It can be integrated with the qualitative abstraction tool~\cite{TiwariKhanna02:HSCC} to generate refined abstractions of hybrid systems with linear continuous dynamics and we illustrate this on a collision-avoidance example from automobile cruise control problem, which was handled completely automatically by our tool.
