Induction Heating Technology and Its Applications: Past Developments, Current Technology, and Future Challenges

2013

International audience; Induction heating technology is nowadays the heating technology of choice in many industrial, domestic, and medical applications due to its advantages regarding efficiency, fast heating, safety, cleanness, and accurate control. Advances in key technologies, i.e. power electronics, control techniques, and magnetic component design, have allowed the development of highly reliable and cost-effective systems, making this technology readily available and ubiquitous. This papers reviews induction heating technology summarizing the main milestones in its development, and analyzing the current state-of-art of induction heating systems in industrial, domestic and medical appl…

A DC current transformer for large bandwidth and high common-mode rejection

1999

A review of known magnetic-coupled current-sensing techniques is presented, Subsequently, a novel technique is introduced, based on a configuration discussed in a previous paper. The previous technique made use of a galvanomagnetic device (Hall effect sensor) to sense the magnetization of a current transformer core, so that the sum of the Hall voltage and the voltage across the secondary shunt resistor would yield a faithful copy of the input current. The technique described in this paper makes use of the same principle to obtain a high bandwidth (from DC to 1 MHz) and very high common-mode rejection current transformer, without the need for a Hall effect probe. This is achieved by subtract…

Neural Sensorless Control of Linear Induction Motors by a Full-Order Luenberger Observer Considering the End Effects

2012

This paper proposes a neural based full-order Luenberger adaptive speed observer for sensorless linear induction motor (LIM) drives, where the linear speed is estimated with the total least squares (TLS) EXIN neuron. A novel state space-vector representation of the LIM has been deduced, taking into consideration its dynamic end effects. The state equations of the LIM have been rearranged into a matrix form to be solved, in terms of the LIM linear speed, by any least squares technique. The TLS EXIN neuron has been used to compute online, in recursive form, the machine linear speed. A new gain matrix choice of the Luenberger observer, specifically taking into consideration the LIM dynamic end…

Remote programming of network robots within the UJI Industrial Robotics Telelaboratory: FPGA vision and SNRP network protocol

2009

This paper presents the UJI Industrial Robotics Telelaboratory, which lets Ph.D. and Master’s degree students perform robotics and computer vision tele-experiments. By using this system, students are able to program experiments remotely via the Web, in order to combine the use of a field-programmable gate array (FPGA) to provide real-time vision processing, a conveyor belt, and a Motoman industrial manipulator. This paper introduces the novel SNRP protocol (i.e., Simple Network Robot Protocol), which permits the integration of network robots and sensors within an e-learning platform in a simple and reliable manner. As long as the students are able to interact remotely with a real robotic sc…

The regional planning of sociosanitary services: methodologies and techniques of analysis

1982

In the field of sociosanitary planning, procedures have often, been fragmentary and disorganized, and the instruments of analysis and forecasting rudimentary. The utilization of models offering those who have to take the decisions an organized approach to the problem therefore represents an obligatory attempt, although there is some disagreement over the utility of their use. Accordingly, in order to understand and describe the mechanisms of the complex set of interacting elements that make up the sociosanitary services, and also to identify opportune means of intervention, this work gives an account of some general principles that make it possible to face problems of organization and contr…

Latest advancements in manufacturing systems at NAMRC 45

2017

Latest manufacturing technologies are more prevalent thanbefore due to recent industrial revolution (or Industry 4.0), continu-ous business decentralization and needs for better overall resourceefficiency and effectiveness. Manufacturers are competing in aglobal, dynamic marketplace that demands excellence in qual-ity and service, throughput, innovativeness, agility in production,short response time to changing markets, and tight profitable mar-gins. In the 21 st century, manufacturing will be gradually pushedtowards a distributed environment with increasing dynamism oruncertainty. It is envisioned that Cyber-Physical Systems (CPS),Cloud Manufacturing, Internet of Things, and Big Data Analy…

Optimization methods for complex sheet metal stamping computer aided engineering

2010

Nowadays, sheet metal stamping processes design is not a trivial task due to the complex issues to be taken into account (complex shapes forming, conflicting design goals and so on). Therefore, proper design methodologies to reduce times and costs have to be developed mostly based on computer aided procedures. In this paper, a computer aided approach is proposed with the aim to offer a methodology able to solve very complex sheet metal stamping processes, in particular a progressive design approach based on the integration between numerical simulations and optimization methodologies is presented. In particular, Response Surface Method, Moving Least Squares approximation and Pareto optimal s…
