The origins of information fusion, a rapidly growing field within the domain of information technologies, can be traced back to developments in a vast array of disciplines. However, it has had the most impetus for growth from the defense arena. Industrial applications, especially in the area of robotics, have begun to surface prominently. The paper first introduces the field of information fusion addressing the questions of what, why, when, and how. This is followed by a brief listing of the various taxonomies that have found currency in this field. In keeping with the theme of the conference, a review of some typical industrial applications is presented next to illustrate the scope and potential benefits of information fusion in this domain.

The paper presents simulation and experimental results obtained from an indirect fuzzy vector controlled induction motor drive under varying operating conditions like step change in speed command and step change in torque command. The superiority of fuzzy controller over conventional controllers in handling nonlinear system such as an induction motor has been effectively demonstrated by comparing the response of the drive system using fuzzy controller with that using a PI controller. The drive system is implemented with a Pentium PC, which uses a high performance data acquisition card for current/speed sampling and to generate the appropriate signals for the control of inverter switches. The present work exploits the advantages offered by a PC based implementation such as user friendliness, ease of programming and minimal amount of hardware circuitry required.

Online transient stability assessment (TSA) of a power system is not yet feasible due to the intensive computation involved. Artificial neural networks (ANN) have been proposed as one of the approaches to this problem because of their ability to quickly map nonlinear relationships between the input data and the output. In this paper a review of the previously published papers on TSA using ANN is presented. The paper also reports the results of the application of ANN to the problem of TSA of a 10 machine 39 bus system.

The genetic algorithm (GA) is emerging as a powerful optimization tool and has recently been applied in a few fields. This paper illustrates the use of GA for the design of controller parameters of a separately excited DC motor drive. The design criterion is modified as an optimization problem and the general rules of GA are applied. In the proposed GA, a novel selection procedure is adopted by combining roulette wheel selection with elitism, resulting in faster convergence to the optimal solution. Simulation of the DC drive is carried with optimized values of controller parameters and the dynamic response of the drive confirms the validity of the new disposition.

Designing an optimal network requires careful optimization of conflicting requirements. It is an NP hard problem. Traditional approaches to this problem have been based either on heuristics or on rigorous mathematical programming, queuing theory and network flow concepts. In this work, the authors describe the use of the multi-objective genetic optimization technique to obtain a Pareto front-a set of solutions which are optimal with respect to a set of constraints and noninferior to each other-for the network design problem. A prototype is developed and the simulator is currently being tested on different sets of inputs.

Placing thousands of videos into multiple storage disk arrays is considered a tedious but major task in the centralized video-on-demand system. This time-consuming task is handled by experienced operators. The solution is hence sub-optimal and operator-dependent. In this paper, a genetic algorithm (GA) is proposed to tackle this problem and to allocate the video automatically. The advantages of using GA are its elegance and simplicity of procedures, as well as the ability to handle different system constraints and optimize the multiple objectives.

Position and speed estimation algorithms for a synchronous motor are presented in this paper. Its principle is inspired from two existing techniques. The aim is to elaborate an estimator that is able to cancel any initial position error and be robust toward DC disturbance. This latest property is realized by using an improved integrator in the estimation procedure. Simulation and experimental results are presented to show the realization of the objectives.

In this paper we propose a technique for the design and development of an automatic visual inspection system for identification of surface defects produced in the steel industry. The proposed DSP based system is implemented using an interconnection of four subsystems: (i) sensing, (ii) data acquisition, (iii) feature (content) extraction and (iv) feature comparison. The system is based on identification of defects using content-based matching of query image with those of database images. The query image is the on-line grabbed image by CCD cameras. The database (off-line) is prepared for all the expected query image by extracting relevant features. An image histogram is used for feature extraction. The computational complexity and storage requirements are reduced by decomposing histogram using wavelet transform. The root mean square (RMS) metric is used for distance calculation.

Previous works have shown the power design effectiveness of novel H-bridge-based DC-DC boost conversion structure, as well as the feasibility of real-time DC-link voltage adaptation to inverter load, in battery-supplied AC motor drives. In this paper a novel test bench has been developed, suitable for power loss measurements in high-efficiency bi-directional DC-DC converters. In order to allow for quasi-direct measurement of the lost power, the concept is to operate the converter by input current having constant module, handling alternating energy flow between two large capacitor banks at given input/output DC voltages. Accordingly, the input current reference is a low frequency (65 Hz) rectangular-wave, whose duty-cycle is regulated by suitable voltage loop due to constant module operation. Except for added large capacitor banks' losses and other secondary effects related to 65 Hz operation, the input DC power supply is shown equivalent to conversion losses at given DC working point. The results point-out the high efficiency of the conversion structure well matched with simple analytical models.
