Control of infinite Symbolic Transition Systems under partial observation

We propose algorithms for the synthesis of state-feedback controllers through partial observation of infinite state systems modelled by Symbolic Transition Systems. We provide models of safe controllers both for potentially blocking and non blocking controlled systems. To obtain algorithms for these problems, we use abstract interpretation techniques which provide over-approximations of the transitions set to be disabled. To our knowledge, with the hypotheses taken, the improved version of our algorithm provides a better solution than what was previously proposed in the literature. Our tool SMACS allowed us to make an empirical validation of our methods to show their feasibility and usability.
