A new static analyzer is described, based on the analyzer Fluctuat. Its goal is to synthetize invariants for hybrid systems, encompassing a continuous environment described by a system of possibly switched ODEs, and an ANSI C program, in interaction with it. The evolution of the continuous environment is over-approximated using a guaranteed integrator that we developped, and special assertions are added to the program that simulate the action of sensors and actuators, making the continuous environment and the program communicate. We demonstrate our approach on an industrial case study, a part of the flight control software of ASTRIUM’s Automated Transfer Vehicle (ATV).
