Compositional Specification of Controllers for Batch Process Operations [chapter]

K. Lano, P. Kan, A. Sanchez
1998 Lecture Notes in Computer Science  
It extends previous work by providing a non-trivial specification for the top-level polling loop of a control system, and defining composition techniques for controllers.  ...  Common features of these operations enable us to provide a generic method for the formalisation of controllers for a large class of such systems, using B and procedural controller synthesis.  ...  That is, where the components of the system are fixed in their relationships with each other. The steam boiler and pasteurisation plants are examples of such systems.  ...
