Timing and synchronization play a key role in cyber-physical systems (CPS). Precise timing, as often required in safety-critical CPS, depends on hardware support for enforcement of periodic measure, compute, and actuate cycles. For general CPS, designers use a combination of application specific integrated circuits (ASICs) or field programmable gate arrays (FPGAs) and conventional microprocessors...
PTIDES, a programming model for distributed real-time systems, was proposed previously. The model captures both the functionality of the system and the desired timing of interactions with the environment. The PTIDES simulator supports simulation of both of these aspects. In this work, we focus on the PTIDES development environment in the context of applications drawn from the control of electric power...
A research prototype of a control system based on smart transducers is described. The smart transducers are self-configuring and support a wide variety of sensors and actuators. Closed loop control has been demonstrated based on peer-to-peer communications.Each smart node consists of three modules:1. A communication transceiver allows selection of wired or wireless communication media.2. A common...
