Dynamic verification of hybrid systems

Abstract

In the recent decade we face aggressive replacement of analog control loops with digital ones. Even for critical systems there are ongoing projects for digital control: “Smart Grids” in power industry, “Integrated Modular Avionics” in aerospace, “Smart Fabrics” in manufacturing, etc. Introduction of large scale digital control channels raises the risks of faults that might result in heavy losses. Those risks call for new methods of analysis and verification, including modeling hybrid systems and model-based verification. The paper overviews a number of existing approaches to verification of hybrid systems and introduces architecture of a test bed for dynamic verification of models of hybrid systems.
