We present a specification approach of secured systems as transition systems and security policies as constraints that guard the transitions. In this context, security properties are expressed as invariants. Then we propose an abduction algorithm to generate possible security policies for a given transition-based system. Because abduction is guided by invariants, the generated security policies...

This paper describes a combination of techniques from control engineering and formal methods in order to specify and implement control systems for hatch process operations. 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. Batch process operations are common in industrial pra...

This paper presents a survey of recent research in cooperative control of multivehicle systems, using a common mathematical framework to allow different methods to be described in a unified way. The survey has three primary parts: an overview of current applications of cooperative control, a summary of some of the key technical approaches that have been explored, and a description of some possi...
