Design of a Supervisor Platform for Movable Bridges

Developing supervisory controllers for high-tech systems is an error-prone and laborious process. Formal methods can help in the development process by providing means to mathematical prove the correctness. One such formal method is supervisor synthesis, where a correct-by-construction supervisor is synthesized from a model of the plant and a model of the requirements. In this paper, supervisor synthesis for a family of similar systems is investigated. To this end, a graphical modeling method based on standardized modules is presented. A prototype tool has been developed that illustrates the proposed method in the development of supervisors for movable bridges. Using this method, the models for a family of seventeen bridges have been developed.
