BCS-FACS Evening Seminar Series -- Joint Event with BCSWomen Specialist
Group

           Design verification for control engineering

                 Professor Ursula Martin

               Queen Mary University of London

                    9 November 2006
                    5.45pm start

               BCS London Offices
               First Floor,
               The Davidson Building
               5 Southampton Street
               London WC2E 7HA


In the first part of this talk I'll introduce control engineering as a
new domain of application for formal methods. I'll discuss design
verification, drawing attention to the role played by diagrammatic
evaluation criteria involving numeric plots of a design, such as
Nichols and Bode plots. I'll show that symbolic computation and
computational logic can be used to discharge these criteria and
provide symbolic, automated, and very general alternatives to
these standard numeric tests, and illustrate our work with
reference to a standard reference model drawn from military
avionics.

At the heart of this work is the observation that control systems
based on linear differential equations exhibit "program-like"
phenomena such as loops and sequential composition, which
allows the development of a Hoare-style logic. While trying to
understand this phenomenon we hit upon a new abstract
presentation of Hoare Logic based on categories with feedback,
which can also be used to capture extensions of the standard
Hoare logic for while programs, e.g. the extension with pointer
manipulations via separation logic.
