Abstract:

In this paper, we present a systematic approach to transform a set of plant models and requirement models into a tree-structured multilevel discrete-event system to which multilevel supervisory controller synthesis can be applied. By analyzing the dependencies between the plants and the requirements using dependency structure matrix techniques, a multilevel clustering can be calculated. Since one of the major drawbacks of synthesizing supervisory controllers is state space explosion, multiple attempts exist to overcome this computational difficulty, such as modular, hierarchical, decentralized, and, recently developed, multilevel supervisory control synthesis. Unfortunately, the modeler needs to provide additional information as input for most of these non-monolithic synthesis procedures. For those supervisory control synthesis procedures that require additional information, no systematic approach exists in literature to transform any set of plant models and requirement models to the appropriate input needed for a particular synthesis procedure. The presented approach is applied to a model of a lock and a model of an MRI scanner patient support table.
