Wireless communication is currently the trend in industrial environments, reducing costs and allowing the creation of applications that were impossible with legacy technologies. In this respect, the WirelessHART specification is emerging as a standard solution. Despite the direct benefits, a WirelessHART network exhibits a series of technical (reliability, energy consumption, tolerance to failures,...
Ethernet field bus has been designated as CAN successor both in automotive and agricultural applications by many international councils because of its high throughput and of the possibility to reuse standard technologies like the TCP/IP stack for a better integration with Internet of Things paradigm. This paper would like to present an essential element for the coexistence of this nets, necessary...
Multivariate Statistical Process Control (MSPC) techniques require process stationarity as a main rule for design and monitoring. However, a critical process such as Boiler and Turbine-Generator units of Thermoelectric Power Plants, which is a multivariable complex system, features different types of non-stationary behavior and operational modes with constant changes of set points of key performance...
Synchronized phasor measurements have recently become one of the key topics in power system research. In order to utilize the new technology to its full potential, many issues need to be addressed. This paper focuses on the problem of synchrophasor measurement precision. A wide range of techniques aimed at the reduction of Gaussian noise present in synchrophasor data are considered. It is shown that...
In this study, in order to develop the lane keep assistance using expansion of body schema by combination of TENS (Transcutaneous electrical nerve stimulation) and view information, the effect to the driving skill on each condition is verified. In the six mode (2 visual × 3 stimulus), participant drive the test course. In the end, it is clearly that driving skill was positively affected by TENS and...
This paper presents a literature review about unbalance in power systems and a case study about unbalance measurements in the Main Interconnected Network (MIS) of Oman. A review of unbalance causes, negative impacts, mitigation techniques, quantification indices and limits are presented. Moreover, voltage and current unbalance measurements at three grid stations that supply the three main industrial...
In this paper a Model Predictive Control (MPC) method for torque control of a Permanent Magnet Synchronous Motor (PMSM) is presented. The proposed approach takes into account constraints on voltages and currents, and allows the use of modulation techniques that eliminate the side effects caused by the direct transistor actuation performed by Model Predictive Direct Torque Control (MP-DTC) approaches...
This paper presents approximate methods to estimate iso-values in 3D thermal model reconstruction of indoor environments. The input data is represented in the form of registered point clouds with added temperature information obtained using 3D laser scanner and thermal imaging camera. They are then registered to the common coordinate system using SLAM6D. Marching cubes based algorithm for point cloud...
Most of automation systems in industry are based on Programmable Logical Controllers (PLCs) due to its reliability and immunity to industrial environments. Besides, PLCs's flexibility and capabilities have allowed human to automate a huge number of industrial processes. In this paper a new multilevel graphical and modular approach is proposed for programming industrial PLCss. Traditional programming...
This paper proposes a new model for state of charge estimation in Ni-Cd batteries, considering the various definitions of capacities and efficiencies that take place in the charging and discharging of the battery. First, the main variables used to determine the capacity of an electrochemical battery are described. Second, coulombic efficiency in charging and in discharging processes is studied. Then,...
Interoperability between shop floor devices and upper layer systems is a key challenge for enabling Internet of Things in industrial applications. Standardized protocols such as IPv6, CoAP, and XML can be used to address this issue. Widely used XML-based technologies such as SenML, EEML, OPC-UA as well as others rely on XML to be able to support a wide range of sensor and actuator applications. However,...
The use of loadable systems whose functionality may be changed or updated using onboard loadable software has become one of the most important improvements in aircraft systems design, and has an important impact in the aircraft production process. The current paper describes the design and implementation of a software data loading application for avionics equipment over an AFDX network, developed...
Cyber-physical systems concept supports the realization of the Industrie 4.0 vision towards the computerization of traditional industries, aiming to achieve intelligent and reconfigurable factories. Standardization assumes a critical role in the industrial adoption of cyber-physical systems, namely in the integration of legacy systems as well as the smooth migration from existing running systems to...
The Ant Colony System (ACS) is a well-known bio-inspired optimization algorithm which has been successfully applied to several NP-hard optimization problems, including transportation network optimization. This paper introduces a method to improve the computational time required by the algorithm in finding high quality solutions. The purpose of the method is to predict the best termination iteration...
Microgrids have been identified as a key instruments in solving energy security, environmental sustainability and energy equity problems faced by developing countries. Furthermore, the opportunity exists for these countries to lead the way in terms of microgrid technology due to the lack of preexisting conventional large-scale generation and inherent support infrastructures found in more economically...
By introducing approaches like the “Smart Factory” and the “Internet of Things”, companies try to ready their manufacturing systems for the needs of the future. The aim is to increase the changeability of these systems through intelligent and self-configuring devices. Prerequisite is an appropriate communication capability down to the lowest sensor level, which is, however, difficult to achieve in...
