Continuous real-time water parameters monitoring is a necessity in the context of contemporary water resources management. There is an important research direction towards the development of monitoring systems, which make use of wireless sensor networks for water parameters acquisition. In this paper, we present our on-going work and preliminary findings on(More)
This paper details on an advanced analysis of a Variable Reluctance Machine, designed to be used for light electric vehicle propulsion. The goal is to setup a Field Programmable Gate Array (FPGA) based Processor-in-the-Loop simulation test bench for the proposed machine, in such way, that emulates the real machine and control unit as close as possible.(More)
The advent of portable devices has a significant impact on the manufacturing industry. Remote programming, monitoring, diagnosis, debugging and configuration are now possible by using off-the-shelf PDAs or cellular phones. In a similar manner, education for certain fields of electronics will have to also move forward, to embrace new technologies not so(More)
This paper presents a rapid control prototyping technique for a speed controlled Switched Reluctance Machine. The control is developed in LabVIEW FPGA and runs on an R-series board by National Instruments equipped with a Kintex-7 FPGA chip. The control is designed and simulated in real-time using look-up tables, with data provided by finite element method(More)
The paper details an advanced analysis of a Permanent Magnet Synchronous Machine, as traction motor for light electric vehicles. The focus of the paper is to create a real-time model in the loop (RTMiL) simulator based on Field Programmable Gate Array (FPGA). By this, the gap between the simulated models and the behavior of the real machine and its(More)

The analysis is ran on a Kintex-7 FPGA using an R series board from National Instruments. The real time simulation model is designed in LabVIEW FPGA and(More)
The paper describes step by step the process of constructing and testing real-time tool for analysis of a bidirectional Buck-Boost converter supplying a Permanent Magnet Synchronous Machine (PMSM), as a traction motor for light electric vehicles. This converter was developed to be used as a controlled energy transfer equipment between the main energy source(More)
This paper presents a platform developed for in production testing of modular embedded systems. These systems are flexible and low cost, with respect to production and maintenance. However, they require a complex testing process, in order to reduce the flaws in the production process and increase the rate of certified modules. For the manufacturers, modular(More)
Wireless transmission is, broadly speaking, considered unreliable and unstable. For real-time applications, redundancy must be counted as a solution for preventing system unavailability. In this paper a testbed comprised of three National Instruments USRP-RIO platforms (two acting as access points, and one as a client station) was set in order to test the(More)
Water management is an important part of the monitoring of the natural environment. For many years water managers relied on field measurements for water quality evaluation. However this process is being revolutionized through the introduction of new technologies such as sensor networks. Discharge is one of the most important parameters in water quality(More)
