Using HyTech to Synthesize Control Parameters for a Steam Boiler

Thomas A. Henzinger and Howard Wong-Toi

We model a steam-boiler control system using hybrid automata. We provide two abstracted linear models of the nonlinear behavior of the boiler. For each model, we define and verify a controller that maintains the safe operation of the boiler. The less abstract model permits the design of a more efficient controller. We also demonstrate how the tool HyTech can be used to automatically synthesize control-parameter constraints that guarantee the safety of the boiler.
