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.

In this paper, the authors develop an analytical criterion for determining the stabilizing gains of a digital control system. The criterion is based on analysis of the behaviour of a real polynomial X(u) constructed from the plant transfer function G(z). It is shown that the real zeros u/sub i/ of X(u)/spl isin/(-1, +1) and the signs of X/spl dot/(u)|/sub u=ui/ determine the range of stabilizing gains K completely, and in closed form. Besides providing a nongraphical and computationally simpler alternative to the Nyquist criterion and root locus techniques, this solution is a first step towards investigating stabilizability by higher order controllers.

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 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.

Flexible manipulators possess a lot of advantages over their traditional rigid link counterparts, like less weight, less power input, higher speed of response etc. But efficient control methods are required to control such a system. The strategy adopted here is to control the manipulator using the nonlinear model till the required terminal joint angle is reached. In the vicinity of the terminal joint angle both the nonlinear and the linearized model are used. Use of the nonlinear model ensures tracking and linear model damps the vibrations. Variable structure control in sliding mode has been used for both the models. This technique has been applied to a single link flexible manipulator.

Although the desirability of active filters is universally accepted, equipment cost can still be an impediment for usage. This aspect can be somewhat redeemed by incorporating multiple mitigatory functions on the same hardware platform. In this paper, the inclusion of two compensatory functions on a single STATCOM is discussed. All analytical designs are supported by experimental results.

Mathematical model of the universal motor and PWM AC chopper is derived and the behavior of the system is studied by simulation. Mains power factor, motor speed, and current are analyzed for different load conditions. Harmonic analysis of the motor current and voltage are given and compared with phase control technique. Experiments are made to verify the effectiveness of the system. According to the experimental results, both simple hardware design and good speed response can be attained.
