The authors present an ATE system designed for teaching practices about programmable electronic instrumentation, by means of GPIB and VXI instruments connected to a local area network (LAN). The aim of this system intended for students of electronic engineering, is the introduction of more relevant technologies involved in hardware instrumentation for ATE applications, besides the handling of their software environments for developing programs.

The well-known pq theory, its extension version, and other power theories are compared in terms of their performance criteria in case of harmonic compensation by using shunt active filters. The analysis is based on the space vector notation and supported by results of computer simulation.

A single-phase H-bridge transistorised converter intended for front-end (FE) power conversion at a high power-factor and a constant desired output voltage has been analysed. Based on the desired boost-mode operation of the converter, the average state-space model has been derived from the basic circuit equations. Equilibrium points of operation of the converter have been obtained from the state-space model. As the converter is intended for use as a voltage source for an inverter, the requirement of maintaining a constant DC voltage at its output becomes a necessary criterion. Two feedback schemes for controlling the output voltage in closed-loop have been designed. Their performances have been compared by simulation studies. Some experimental studies on the converter operating in open-loop have been made and results obtained in the boost-mode of operation.

In this paper, a new real-time on-line batch scheme recursive LS approach is proposed for physically-based parameters identification of nonlinear continuous-time plant using Hartley modulating functions (HMF) and facilitated by interactive real-time toolbox. The method is implemented by moving a fixed window size of time series data one step forward at each sampling time and by updating recursively the regressand vector and regression matrix of the system HMF model that consists of updating the sequential Hartley transforms and spectra for each coming sample of input-output signals. The method is applied on a separately excited DC motor and load plant to examine the performance and potential of the proposed real-time on-line identification approach.

Series resonant converters find application in high voltage power supplies where the large transformer parasitics have to be accounted for. This paper deals with the analysis, simulation and design of the phase modulated series resonant converter. Steady state analysis for the above resonant frequency operation is presented. Two modifications, one for extending the zero voltage switching range and the other providing inherent short circuit protection are also introduced. Experimental results on a laboratory model are shown to verify the design procedure.

This paper proposes a new method of detecting type of faults on a three phase transmission line by using Petri net theory. A marked graph is presented by using various phase sequence combinations for identifying phase to ground and phase to phase faults. The proposed methodology is more efficient than the traditional approaches specially when the complexity of the problem increases. This model may also be extended to identify other types of faults also.

The challenge in the endpoint control of flexible manipulators is of obtaining an exact model of the nonlinear flexible system and then simulating it for further analysis. But being an infinite dimensional, they pose problems in terms of predicting the behaviour and also exact mathematical representation. This problem of obtaining an exact model can be solved if the behaviour of the flexible link system can be represented by a neural network, which would help further simulation, analysis and control thus eliminating the requirement of the exact mathematical representation of the system.

This article addresses the problem of recovering a tridimensional scene from only one uncalibrated static camera and images from planar mirrors. We present a linear solution for 3D Euclidean reconstruction based on multiocular geometry, epipolar geometry and projective geometric properties. From the recovered points of the scene we can obtain information related with distances, areas, curvatures, dimensions and even volumes of its objects. A system based on this technique could be applied on the industry, in tasks of great importance, such as the quality tests and metrology inspection. The system is simple, low cost and could achieve good performance.

The paper deals with the neural net and fuzzy models as universal approximators. Four types of models suitable for identification are presented: the nonlinear output error, the nonlinear input error, the nonlinear generalised output error and the nonlinear generalised input error model. The convergence properties of all four models in the presence of disturbing noise are reviewed and it is shown that the condition for an unbiased identification is that the disturbing noise is white and that it enters the nonlinear model in specific point depending on the type of the model.
