Real Time Distributed Control of Variable Speed Drive System in Cyber Physical Framework

Distributed Real-Time Software for Cyber-Physical Systems

Real-time embedded software today is commonly built using programming abstractions with little or no temporal semantics. This paper addresses this problem by presenting a programming model called PTIDES that serves as a coordination language for model-based design of distributed real-time embedded systems. Specifically, the paper describes the principles of PTIDES, which leverages network time ...

Agent based distributed control of islanded microgrid - Real-time cyber-physical implementation

In the hierarchical control of an islanded microgrid, secondary control could be centralized or distributed. The former control strategy has several disadvantages, such as single point of failure at the level of the central controller as well as high investment of communication infrastructure. In this paper a three-layer architecture of distributed control is given, including the device layer, ...

Real-Time Wireless Control Networks for Cyber-Physical Systems

Wireless control systems represent a new frontier of cyber-physical systems. Rapid adoption of wireless sensing and actuation standards has demonstrated the feasibility of reliable wireless communication for industrial automation. However, wireless control networks face significant challenges in meeting real-time communication requirements of control systems. Furthermore, close coupling between...

Poster: Adaptive Real-Time Cyber Physical System Software

We present our programming constructs that allow developers to gain a control on timing aspect in enforced adaptation decisions in real-time Cyber-Physical System (CPS) software. CPS operation often depends on the environmental conditions, and CPS software must adapt to the changes in these conditions. In CPS software a control-loop is run every 1-10ms or even faster, forcing the adaptation to ...
