Quality control is of utmost importance in the metal industry. It requires online measurement and inspection systems which provide precise feedback to closed-loop controllers in industrial facilities. In rolled products, shape is one of the main quality criteria. In this work a low-cost, real-time 3D shape measurement system for long, flat-rolled products based on laser triangulation is proposed. The system provides online measurements of two geometrical features of the shape of rolled products: flatness and width. The proposed system is based on 3D surface reconstruction of rolled products with which flatness can be measured accurately and continuously across the whole width of the strip. Three-dimensional surface reconstruction provides highly width accurate measurements not only of flat products, as do most other systems, but of non-flat products. The accuracy of the laser extraction method used to reconstruct the surface of the rolled products is evaluated, as well as the online performance of the system.

Effect of gradient force on collection of diesel exhaust particles (PM) has been experimentally observed. Gradient force can drive particles only when they are in non-uniform electric field. A needle electrode was used to generate a gradient force. Observation of trapped PM on the needle electrode suggests that AC voltage application is more effective to keep the PM on the needle electrode. Is should also be noted that pearl chain formation of PM is observed, suggesting that the gradient force is suppressing the dust reentrainment. The results of this study suggest that ESP based on gradient force is feasible for collection of PM from diesel exhaust.

This work is an attempt to undertake the development and implementation of a new and practical fuzzy switching bang-bang controller for automation and appliance industry. Compatible with the structure of an enhanced bang-bang controller, a two-input fuzzy switching bang-bang controller with five rules is proposed. The key advantage is the ease of the design and flexibility. The idea is based on constructing a fuzzy switching control law which is functionally analogous to an enhanced bang-bang controller. The fuzzy switching bang-bang controller is implemented in real-time, using the position control of a brushless dc servo drive system as a testbed. The testbed was built and tested in the laboratory using a collection of tools that include both off-the-shelf hardware (dSPACE DSP DS1104) and software (MATLAB/Simulink). Experimental results show that the fuzzy switching bang-bang controller produces adequate control performance, particularly in handling nonlinearities and external disturbances. The efficacy of the fuzzy switching bang-bang controller is demonstrated by its positive results, when compared with an enhanced bang-bang controller. This paper also presents a hardware platform used during the implementation stage.

High currents leaked to earth, leads to an electric field, which can be capable of breaking down the dielectric strength of the soil. When this happens, the ionization phenomena takes place, which reduce the grounding system impedance and modify its performance. In this paper, a computational model for transient performance of grounding systems is presented. The model is capable of simulating soil ionization and is based in a transmission line approach. The grounding system transient analysis is carried out in the frequency domain. The computer model developed was used to study the performance of vertical rods and grounding grids of different sizes. In every case, different electric field magnitudes and soil resistivity were used, currents of different frequency components and magnitude values where used as well. The obtained results presented here, were compared and validated with other computer model results and measurements published in the literature.

In this paper a voltage controlled variable capacitance is being proposed as a method for non-contacting measurement of electric fields. There are several microelectronic devices that can be utilized for that purpose: a varactor (a.k.a. varicap), a MOS (metal-oxide-semiconductor) or a MIS (metal-insulator-semiconductor) structure. The construction that has been tested and presented in this paper is based on a varactor diode. Although numerous non-contacting instrument designs are widely available, they either lack precision (meters utilizing Kerr or Pockel effect, rotating vane fieldmeters, fieldmeters with mechanically vibrating sensors) or are relatively expensive and complicated (electrostatic voltmeters). Other types of electric field meters such as capacitive coupling or induction instruments rely on variation of the electric quantity that is being measured, therefore they are not useful for detection and quantification of static (DC) electric charges and fields. The sensor used in the experiment described in this manuscript can be used for the DC and AC electric field measurements. The construction is very simple, therefore inexpensive, and it can be easily miniaturized.

White light emitting diode (LED) with high brightness has attracted a lot of attention from both industry and academia for its high efficiency, ease to drive, environmental friendliness, and long lifespan. They become possible applications to replace the incandescent bulbs and fluorescent lamps in residential, industrial and commercial lighting. The realization of this new lighting source requires both tight LED voltage regulation and high power factor as well. This paper proposed a single-stage flyback converter for the LED lighting applications and input power factor correction. A type-II compensator has been inserted in the voltage loop providing sufficient bandwidth and stable phase margin. The flyback converter is controlled with voltage mode pulse width modulation (PWM) and run in discontinuous conduction mode (DCM) so that the inductor current follows the rectified input voltage, resulting in high power factor. A prototype topology of closed-loop, single-stage flyback converter for LED driver circuit designed for an 18W LED lighting source is constructed and tested to verify the theoretical predictions. The measured performance of the LED lighting fixture can achieve a high power factor greater than 0.998 and a low total harmonic distortion less than 5.0%. Experimental results show the functionality of the overall system and prove it to be an effective solution for the new lighting applications.

The present paper deals with a generalized control strategy for the following multilevel inverters: Neutral Point Clamped (NPC), H-Bridge, and Load Phase Clamped (LPC). The contribution of this work is to develop, in spite of these devices differences, a common control strategy using simple triangular sinus PWM. By applying Petri Network theory, common configurations of these inverters are established. The generation of the trigger commands requires an accurate load current estimation to achieve a safe operating. Results by simulation and by experimentation are shown and discussed to validate the efficiency of the proposed technique.

In this work we have reported low cost solar cells which can be processed to scalability by depositing direct and uniform films using airbrushing, inkjet printing, or spin-coating techniques. We have synthesized single wall carbon nanotubes (SWNTs) by catalytic Chemical Vapor Deposition (cCVD) method, which were subsequently doped with boron for photovoltaic applications. The carbon nanotubes were characterized by Raman spectroscopy, thermal gravimetric analysis (TGA), transmission electron microscopy (TEM) and x-ray photoelectron spectroscopy (XPS). The solar cell devices were fabricated by depositing a uniform dispersion of b-SWNT films on n-Si creating numerous heterojunctions. These studies are the first in which b-SWNTs have been utilized directly for photo-generation.

Due to inherent high efficiency and high power density, high-speed permanent magnet brushless dc motors have been extensively studied and utilized in many fields. Sensorless operation can significantly improve system reliability and reduce the performance variations caused by discrete sensors. From the system point of view it is often necessary to consider sensorless operation at the motor design stage. Among various sensorless commutation techniques available for the PM brushless dc motor drives, the one based on the detection of zero-crossings of the third-harmonic back-EMF is most common. However, duo to the high speed operation, the free-wheeling diodes may conduct by over 300 elec., which has no influence on the detection of the third-harmonic back-EMF zero-crossings. The third-harmonic back-EMF, which is not obscured, is used. In this paper, pertinent motor design considerations with regard to control using the third-harmonic back-EMF are presented. Finite element analysis and experimental results are given to verify the design optimization for the control. Experiments have verified the related theoretical analysis, design method and sensorless control strategy.

This paper analyzes the electromechanical inter-action in a flywheel system with a doubly fed induction machine, used for wind farm power smoothing or grid frequency response control. The grid-connected electrical machine is subject to power control and this can cause it to produce negative damping to the shaft torsional vibration. Resonance must be prevented and the study proposes a solution by coordinating the design of the electrical controller and mechanical shaft. Computer simulations are used to demonstrate the problem and the proposed solution.
