Abstract

Automatic analysis of Hybrid Systems poses formidable challenges both from a modeling as well as from a verification point of view. We present a case study on automatic verification of a Turbogas Control System (TCS) using an extended version of the Murφv; verifier. TCS is the heart of ICARO, a 2MW Co-generative Electric Power Plant. For large hybrid systems, as TCS is, the modeling effort accounts for a significant part of the whole verification activity. In order to ease our modeling effort we extended the Murφv; verifier by importing the C language long double type (finite precision real numbers) into it. We give experimental results on running our extended Murφv; on our TCS model. For example using Murφv; we were able to compute an admissible range of values for the variation speed of the user demand of electric power to the turbogas.
