Abstract
In this thesis, we present such a middleware framework for networked control systems. Central to this framework is Etherware, a message oriented component middleware for such systems. We begin with a detailed description of the design and architecture of Etherware, and illustrate Etherware based development of networked control systems through a fairly complex traffic control testbed application. Building on the middleware, we address safety and security issues in networked control through a detailed scenario in this testbed, implementing safety preserving security overrides. We then address the issue of providing guarantees of overall system behavior in networked control systems. In particular, based on established properties of sub-systems, we prove system-wide guarantees for safety and liveness in the traffic control testbed.
