This thesis addresses the problem of proving the safety of systems described by non-linear dynamical models and hybrid dynamical models. A system is said to be safe if all trajectories of its state do not reach an unsafe region. Proving the safety of systems by explicitly computing all its trajectories when its dynamic is non-linear or when its behavior is described by an hybrid model with non-linear dynamics remains a challenging task. This thesis considers the barrier function approach to prove the safety of a system. A barrier function, when it exists, partitions the state space and isolates the trajectories of the system starting from any possible initial values of the state and the unsafe part of the state space. The set of constraints...
