“…Q. Li 11 investigated delays associated with the use of FF H1 networks within control loops. Y. Pang and H. Nishitani’s 12 research pointed out that the execution time of FBs and the margin time are dominant over communication delays in FF fieldbus. The above-mentioned study showed the variety and diversity of means to achieve that goal.…”

In this paper, the issue of improving control performance of a network-based control system in a different perspective from control algorithms was fully addressed. Some important performance-affecting elements including design of network architecture, configuration, and delay compensation were investigated and some methods presented. The presented design and implementation of a network-based cascade control system with a real laboratory pilot plant involved adopting two different control approaches based on Foundation Fieldbus and Ethernet, respectively. We presented some practically feasible approaches to improve control performance of the system, including improved function block configuration scheme, synchronization control methodology based on IEC61499, output estimation algorithm based on neural network, and methods for reducing network transmission by improving hardware and network architecture. Control effects under the proposed methodologies were also given. Experimental and on-site practice validated these methodologies.

A remote embedded power measuring and supervising system is developed based on the global network.The electric signal such as voltage, current and power for a single-phase two-wire circuit or a three-phase three-wire circuit can be measured by the power measurement device. The center embedded server composed of the embedded Linux OS (Operation System) called as TimeSys [1] and embedded framework with Hitachi microcomputer [2], works as the bridge between users and power measurement devices. RS485 communication bus is designed to connect at most 31 measurement devices to the center server. The web access service based on the network communication interface is provided to enable remote data supervising, comparing, downloading, and so on. The whole system achieves remote supervision and abundant data analysis for energy conversation.
