Reconfigurable Distributed Network Control System for Industrial Plant Automation

Abstract

Use of advanced communication technologies, highly integrated control, and programming platforms drastically increases the performance of industrial control systems. That is the case of Motronic, where the synergistic collaboration between industry and academia has led to an advanced distributed network control system. To be commercially successful, it needs to have a low cost and to be robust, even if this requirement implies that it is a custom design and not based on previously existing commercial solutions. Use of standards and off-the-shelf products lower development costs, but usually raise production costs. In this paper, we show that, in certain applications, design of a new system from scratch is more advantageous. This system comprises a set of dynamically reconfigurable local controller nodes, a graphical programming environment, a remote supervision and control system, and a fault-tolerant fiber optical network. TCP/IP connectivity is provided by the use of a local gateway. Motronic is currently being applied in the integrated control of large production plants and in energy and power management industries.

Performance Analysis of a Real-Time Control Network Test Bed in a Linux-Based System With Sporadic Message Arrivals

“…Once a message is scheduled, it cannot be blocked at the scheduler again. Thus, an estimate of the worst-case blocking at the local scheduler is determined as (2) where " " indicates a worst-case estimate. It is necessary to estimate kernel delay, , since it cannot be explicitly bound.…”

Opportunities and Challenges of Wireless Sensor Networks in Smart Grid

“…The collaborative operation of WSNs brings significant advantages over traditional communication technologies, including rapid deployment, low cost, flexibility, and aggregated intelligence via parallel processing. The recent advances of WSNs have 0278-0046/$26.00 © 2010 IEEE made it feasible to realize low-cost embedded electric utility monitoring and diagnostic systems [1], [4], [9], [11], [19], [30]. In these systems, wireless multifunctional sensor nodes are installed on the critical equipment of the smart grid and monitor the parameters critical to each equipment's condition.…”
