This paper presents a set theoretic approach that provides a systematic way to formulate and incorporate information into the motor fault detection framework. Based on this set theoretic formulation, a heuristically constrained neural/fuzzy system is then used to learn the exact input/output relation of the fault detection process for a specific motor using measured data. This system is able to provide updated membership functions of the sets which better describe the fault detection problem. To illustrate their proposed methodology, a three-phase induction motor exposed to changing external factors is used for the detection of a friction fault.","PeriodicalId":377136,"journal":{"name":"IECON '98.

However it is often very difficult to spot all possible problems by eye alone. Many systems provide some form of automated checking or automated path generation, but in our experience these are rarely used as they are either too slow or too limited. In order to address these problems we have developed a modular architecture called OXSIM for developing path planning programs. OXSIM explicitly separates out issues of geometric competence from planning competence, so that new ideas in path planning can be quickly tested without a programmer worrying about geometry, and conversely new types of geometry can be added to an existing path planner in a clean way. Most of the existing practical path planning methodologies can be written down in this way. Initial results from OXSIM have been encouraging, and we are now proceeding to tests on a large workcell.","PeriodicalId":377136,"journal":{"name":"IECON '98.

During recent years, virtual reality (VR) has proved its potential for the visualization and interactive manipulation of complex data. This paper describes a process for integrating an interactive VR-based assembly simulation of a digital mockup into an existing CAD/CAM infrastructure. The necessary hard- and software preconditions for the process are explained so that it can easily be adopted by nonVR-specialists. The article outlines how assembly simulation can improve the CAD/CAM procedures and structures, which CAD model preparations have to be carried out and which virtual environment requirements have to be fulfilled. Finally, deficits of existing VR simulation software are discussed and possible solutions and necessary developments are presented.","PeriodicalId":377136,"journal":{"name":"IECON '98.

For the preprocessing purposes of an image, thresholding is a necessary tool. Here, a new method based on minimizing measures of fuzziness is presented. Every pixel in the image and the averaged image have a membership value. Using these membership values entropy measures of fuzziness of image set and averaged image set are calculated. Then, threshold is founded by optimally minimizing calculated measures. The experimental results indicated that the new method has good performance but takes a long time in averaging.","PeriodicalId":377136,"journal":{"name":"IECON '98.

Hereby the operating process is controlled mechanically via cam disks fitting on a line shaft, making sure that all processes maintain their synchronism even in case of breakdown. As a consequence, product conversions need considerable setup time. The use of modular concepts in construction and in drive engineering allows a simple and fast and therefore low-cost product changeover. The use of single drive systems requires the substitution of the mechanically coupled functions by data-processing links. This paper presents a new feeding conveyer of a cartoning machine using two interconnected servomotor drives as well as a collision avoiding strategy. The mentioned strategy has been worked out and is currently being tested on a test bench.","PeriodicalId":377136,"journal":{"name":"IECON '98.

The full-bridge parallel resonant power converter reduces the current stress compared to the half-bridge power converter, so it is presented as a solution to drive lamps over 100 W. The analysis of the full-bridge control based on pulsewidth modulation is presented for HPS and fluorescent lamps. As the inverter input voltage is usually quite high compared to the lamp voltage requirements in steady-state operation, the quality factor of the resonant tank is low, resulting in an appreciable level of reactive current. The PWM dimming control at fixed frequency is proposed when the total current level is acceptable. In this case, while maintaining the transistors' turn-on at zero voltage, the PWM control improves the power converter efficiency by reducing the reactive current. When the reactive current causes an important efficiency reduction, a quasi-optimum control method is proposed that consists of fixing, at each control point, the frequency vs. duty-cycle relation that minimizes the reactive current while maintaining soft turn-on.","PeriodicalId":377136,"journal":{"name":"IECON '98.
