Towards component based design of hybrid systems: safety and stability

We propose a library based incremental design methodology for constructing hybrid controllers from a component library of models of hybrid controllers, such that global safety and stability properties are preserved. To this end, we propose hybrid interface specifications of components characterizing plant regions for which safety and stability properties are guaranteed, as well as exception mechanisms allowing safe and stability-preserving transfer of control whenever the plant evolves towards the boundary of controllable dynamics. We then propose a composition operator for constructing hybrid automata from a library of such pre-characterized components supported by compositional and automatable proofs of hybrid interface specifications.
