Design and Performance of DDS-based Middleware for Real- Time Control Systems

Abstract: Data-centric design is emerging as a key tenet for building advanced data-critical distributed real-time and embedded systems. These systems must find the right data, know where to send it, and deliver it to the right place at the right time. Data Distribution Service (DDS) specifies an API designed for enabling real-time data distribution and is well suited for such complex distributed systems and QoS-enabled applications. It is also, widely known that Control Area Networks (CAN) are used in real-time, distributed and parallel processing.

Evaluation of a Real-Time Distribution Service

Abstract: As control systems become more distributed and they are implemented with smaller hardware and software components, implementing the necessary communication links becomes challenging. There are considerable technical difficulties in guaranteeing upper bounds for latencies in motion or machine control, synchronizing the execution and communication of distributed components, taking corrective action in fault situations and reconfiguring the system.
