Our analysis is based on a novel strict dissipativity notion for such problems, in which a stationary stochastic process replaces the optimal steady state of the deterministic setting. We show that from this time-varying dissipativity notion, we can conclude turnpike behaviors concerning different objects like distributions, moments, or sample paths of the stochastic system and that the distributions of the stationary pair can be characterized by a stationary optimization problem. The analytical findings are illustrated by numerical simulations.en1095-71382025214321457Soc.dissipativity | stochastic optimal control | stochastic systems | turnpike propertyTechnology::600: TechnologyJournal Article10.1137/23M160089XJournal Article
