Dynamic verification of hybrid systems

In the recent decade we face aggressive replacement of analogue control loops with digital ones. There are ongoing projects for digital control even for critical systems: «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 an architecture of a test bed for dynamic verification of models of hybrid systems.
