A General Framework for Modeling and Online Optimization of Stochastic Hybrid Systems

Ali Kebarighotbi, Christos G. Cassandras

We extend the definition of a Stochastic Hybrid Automaton (SHA) to overcome limitations that make it difficult to use for on-line control. Since guard sets do not specify the exact…
