In this paper, development and implementation are presented of a client software package for remote process control. The proposed software is based on a client-server model under an Intranet architecture. The architecture is proposed for a telecontrol system of a real process, which includes the possibility of integrating I/O devices with data networks based on open protocols such as TCP/IP. This protocol allows the implementation of control systems using a low-cost alternative. Also, the Smith predictor is revised for remote control applications over an Ethernet network. Some experiences on a laboratory pasteurization plant are addressed to show both developed controllers and architecture performance.

The success of small satellites has lead to the study of new technologies for the realization of Nano and Micro Launch Vehicle (NMLV) in order to make competitive launch costs. The paper has the objective to define and experimentally investigate the performance of a communication system for NMLV interconnecting the End Systems as On-Board Computer (OBC), telemetry apparatus, Navigation Unit...we propose a low cost Ethernet-based solution able to provide the devices with high interconnection bandwidth. To guarantee hard delays to the Guide, Navigation and Control applications we propose some architectural changes of the traditional Ethernet network with the introduction of a layer implemented in the End Systems and allow for the lack of any contention on the network links. We show how the proposed solution has comparable performance to the one of TTEthernet standard that is a very expensive solution. An experimental test-bed equipped with Ethernet switches and Hercules boards by Texas Instruments is also provided to prove the feasibility of the proposed solution.

Six Degree Of Freedom

This contribution presents a new force control concept for industrial six-degree of freedom (DOF) manipulators, which uses a Hexa platform that provides an active environmental stiffness for all six DOFs. The paper focuses on the Hexa platform and is split into two essential parts: (i) parallel platform construction, and (ii) application of force control with industrial manipulators using a six-DOF environmental stiffness. This mechatronic solution almost gives one hundred percent robustness for stiffness changes in the environment, what guaranties a significant shortening of execution time.

Broadband trunking communication system has been widely used with a variety of industries, such as public transportation security and navigation, etc. Trunking communication is a branch of mobile communication. Because the client of traditional dispatch services based on C/S (client/server) architecture need to install the client software, this paper studies and designs one dispatch client, which is based on B/S (browser/server) architecture.

Key Features

A review of electrochemical reactor systems for the recovery of metals and for pollution control applications is presented. The major engineering factors which influence the design of reactors are evaluated and the key features of two-dimensional and three-dimensional reactor designs are discussed. Some examples of the application of electrochemical reactors to the recovery of metals from dilute solutions are given in the form of case studies, covering both pollution control and resource recovery processes. Finally a comparison is made of the relative technical and economic merits of electrochemical recovery pollution control systems and conventional chemical waste treatment routes.

Training Control

Student access to laboratory experiments is critical in undergraduate engineering courses since it integrates theory and practice. The access of students to such practical examples helps them to understand and apply what is learned. However, due to rapid technological advancement, educational kits can quickly become obsolete. Besides, there are many known commercial platforms for training.Many of them have steep prices, which makes their availability dicult for every student. The present work proposes a low-cost ATMEGA-based system as the main device for an educational tool for training Control System Theory. The system enables the students to test dierent control strategies through the use of a simple educational kit.
