The switching lag-time, which prevents the phase shortage of inverter arms, causes serious distortions of the output voltage of the inverter. This effect is well known as the dead-time effect. Several compensation methods have been proposed to improve the output waveforms. These proposed approaches did improve the inverter's output voltage waveforms. The improved waveforms however still suffer from the zero-crossing phenomenon. A new approach to overcome the zero current clamping in voltage-fed PWM inverters is proposed. This paper describes the analysis of dead-time effect in three-phase PWM inverters and the proposed scheme. The conventional compensation methods, as well as the zero crossing problem, are highlighted. Theoretical analysis and digital simulation were carried out to verify the analysis and the proposed scheme for dead time compensation.

In this paper, the performance of two different sensorless control methods for switched reluctance motor drives based on amplitude modulation techniques are compared. In both the methods, a sinewave diagnostic signal is injected into one of the inactive phases and the rotor position is inferred from the resulting modulated current signal. In the first method, the rotor position sensing is achieved only through hardware means. In the second method, which is introduced in this paper, the diagnostic signal is used to generate an index pulse which occurs every 30/spl deg/ (mech). The rotor position information is obtained at the intermediate positions using the index pulse in conjunction with internal timer available in the microcontroller in order to achieve high resolution. In this paper the position error, resolution, speed range and transient stability of the two methods are systematically analyzed using dynamic model of the 100 V, 500 W, 3000 RPM, 6/4 motor and their advantages and disadvantages are presented. Experimental results are presented in order to validate the two sensorless methods. The analysis results presented in this paper will be useful for the practical design of amplitude modulation based sensorless control schemes for SRM drives.

Fuzzy logic controllers (FC) have been implemented and studied on various types of static power converters. However, their improvement in converters' performance is not clear compared to classical control theory controllers. This is especially true in systems where precise models exist, such as the PWM boost rectifier (PWM-BR). Hence, another use of FC has ensued, which is to tune and adapt controllers synthesized by classical control theory. This paper takes advantage of this trend and proposes an adaptive fuzzy controller (AFC) which offers an improved dynamic response when compared to conventional FC. The AFC adaptive nature is achieved by modifying its normalizing factors, gains, and by using an inner AFC to adapt the output normalizing gain. Thus, the AFC is capable of reducing the PWM-BR overvoltage and settling time by 65% and 80% compared to a conventional FC. Consequently improving the switches' voltage utilization factor by 9.1%. The converter's fast response is attained by using a dynamic space vectors modulation that also improves the converter's voltage utilization by presenting a unity AC-DC gain. The paper presents a complete analysis and design procedure of the AFC and PWM-BR system, together with a detailed and thorough evaluation under transient conditions. All these show the feasibility of the proposed control scheme.

The purpose of this paper is to develop an advanced 3-D profile sensor system which will be able to accurately measure 3-D free-form machined metal surfaces. The proposed sensor system has many advantages as compared with conventional measuring systems. First, a new detecting system of optical ring images utilized by the rotating image detector is developed to measure 3-D profiles in the long measuring range with high accuracy. Second, processing time can be shortened within 0.5 second by using the proposed detecting system. Third, the speckle noise is eliminated effectively by the rotating mechanism. Finally, it is concluded that this sensor system makes it possible to measure the profiles within an accuracy of /spl plusmn/50 /spl mu/m in the measuring range of 100 mm. In this paper, the measurement principle of the proposed sensor system is analyzed and the performance of the system is experimentally measured and discussed not only for both diffuse reflection surface and specular reflection surface, but also for reduction of the laser speckle noise which has direct influence on the measurement accuracy.

The most critical step in railway wagon production is its erection, by which the four modules-floor, two side walls and roof-are assembled to a large Al pipe, with 4 exterior and interior welds. The paper illustrates a project that realises an innovative fully automatic facility for the erection state production process in the railway construction industry. The complete joining operation and the auxiliary processes are carried out automatically. An additional rail system in the interior allows a carrier for the welding torch to be moved, since it is intended that no human operator shall be in the wagon shell during operation. A full quality control system includes a sensor system for verification. The solution is outstanding, especially for the construction of high speed trains, together with a considerable improvement of the working environment, due to no direct contact with fumes and machining particles. The automatic performance also offers the option to join processes as double wire techniques of MIG/TIG combi process. A 15% reduction of the production hours and 25% of total production time for wagon crates is estimated.

One of the problems presented when circuit simulation is used to analyze a complex electromechanical system is the amount of work required to represent each device with an adequate precision level. The calculation process required to customize each model block to represent a particular device is a time consuming task that asks for accurate knowledge of all device and model parameters and of all the trade-offs in the model set-up. The solution presented in this paper uses a general purpose simulation tool, such as SPICE, and develops a pre-processor program able to generate the SPICE input listing, using the models already available for each component or circuit block in the electromechanical system to be modeled. The program G-MES helps the designer in the selection of the best trade-off and the calculation of the selected block or component model parameters in a complete interactive way. Once the system model is completed, G-MES provides a SPICE compatible file, with the model of the complete electromechanical drive system, ready for circuit simulation.

This work deals with the application of a neural network-based controller for tracking the point of maximum power of a photovoltaic (PV) system interconnected to the utility grid. The neural network is used to identify, in real time, the voltage for maximum output power of the system. The controller, through the information supplied by the neural network, generates a control signal that will be applied to a DC/DC (boost) converter in such a way to take the voltage of the system to a value which guarantees the operation of the PV system at maximum power. The boost converter duty-cycle is generated by a PI controller based on the information supplied by the neural network. In order to connect the PV system to the electric distribution system a three-phase voltage source inverter (VSI) is used operating with optimized sinusoidal PWM strategy with harmonics elimination at the output voltage up to the 17/sup th/ harmonic. The inverter uses IGBT as power switches, and is microcontroller operated.

Virtual environments are a new means for human-computer interaction. Whereas techniques for visual presentation have reached a high level of maturity, many of the input devices and interaction techniques still tend to be awkward for this new media. Where the borders between real and artificial environments vanish, a more natural way of interaction is desirable. To this end, we investigate the benefits of integrated speech- and gesture-based interfaces for interacting with virtual environments. Our research results are applied within a virtual construction scenario, where 3D visualized mechanical objects can be spatially rearranged and assembled using speech- and gesture-based communication.

In this paper, a study is presented of how self-organizing ART networks can be used to create a trainable, feature-based real-time 3-D object recognition system. Feature extraction is a well known approach to reduce the number of appearances of a three-dimensional object. Since features are derived from only a small part of the information comprised in the original image, it cannot be assumed that a given set of objects is separable in the reduced feature space. To avoid ambiguities, in general, multiple features have to be integrated in an object recognition system. Since feature extraction can be computationally intensive, a real-time system should evaluate features sequentially and terminate recognition when ambiguities are resolved. This paper gives an analysis of the clustering properties of ART 2A-E networks. It is shown how ART networks can be used to generate meaningful hints concerning the object's identity from ambiguous features by exploiting them up to an optimal degree.

In the past, electrical single spindle drives have been rarely used in textile machines. Only spindles with high power requirement- e.g. cabling machines-are provided with inverter fed induction motors. In the case of spindles with smaller power requirements-for example ring spinning machines-the classical belt drive still dominates. This report describes the development of an economic electrical single spindle drive for textile machines. In addition to manufacturing costs, the demands for a high degree of efficiency and exact speed control have to be considered. A comparison of different electrical motors-and the associated frequency converters-shows the advantages of a brushless DC motor design. The rotor position sensing of the described brushless DC motor spindle drive can be realized without sensors by monitoring the motor voltages.
