This circuit contains a short circuit protection scheme by limiting the IGBT fault current to a lower value through reduction of the IGBT gate voltage and thereby can distinguish a transient from an actual fault. Apart from the short circuit protection, the circuit also protects the IGBT in case of over-temperature. This circuit does not have any speed-up capacitor, differentiating element or latching element, thus giving good immunity towards unwanted noise. The oscillograms presented in this paper confirms satisfactory operation of this circuit.","PeriodicalId":405648,"journal":{"name":"Proceedings of IEEE International Conference on Industrial Technology 2000 (IEEE Cat.

In the present transfer system, a small, fast, 6-Ampere relay is used as a transfer switch. To achieve faster operation, a 6 V-relay coil has been chosen as a low voltage relay coil has a lesser number of turns, implying less inductance. Here the duration of the peak current of the relay coil has been assumed to be the duration for transfer of the load from main to auxiliary source. Only one change over relay contact is enough for the low power transfer switch. The faster relay has minimum physical gap between the contacts. It is not as fast as a static switch, implying relatively larger interruption time, especially at the time of load transfer between mains source to auxiliary. Using suitable speedup circuit, a 6-millisecond transfer time is achieved. This timing tallies with the simulated transfer time.","PeriodicalId":405648,"journal":{"name":"Proceedings of IEEE International Conference on Industrial Technology 2000 (IEEE Cat.

These include process control and quality control in industries such as foodstuffs, beverages, tobacco, perfumery and pharmaceutical. ENOSE is also crucial component in industrial safety (smoke and hazardous gas detection) as well as environmental pollution control. This paper deals with design of an intelligent ENOSE system for the identification of gas/odours using a sensor array and a neural network pattern classifier. Previous researchers have shown that the power of discrimination increases rapidly with the number of sensors in the array whose information potential is very large and the pattern recognition (PARC) method is a clever way to extract this information. The authors show in this paper with the powerful PARC technique, the need of larger array can be compensated. With this view, they design a neural classifier using two different learning approaches and train the network over the responses of surface acoustic wave (SAW) sensors exposed to hazardous vapours like diethyl sulphide (DES) and iso-octane (ISO). Dimensionality of the data set is varied from 1 to 8 by taking different number of sensors. It is found that for a backpropagation trained neural classifier, the optimum number of sensors required for satisfactory classification under noisy conditions is 4 to 5. This is a very limited range beyond which backpropagation has great difficulty in training the neural classifier even with repeated restarts and different weight initializations. To alleviate this problem, hybridization of soft computing tools like neural networks and genetic algorithms promises to provide the design of better intelligent system. The authors propose the use of a genetic algorithm based on a special MRX operator introduced by them and demonstrate very encouraging results with genetically trained neural network model even with larger as well as smaller numbers of sensors.","PeriodicalId":405648,"journal":{"name":"Proceedings of IEEE International Conference on Industrial Technology 2000 (IEEE Cat.

The poles of the discrete time control system could be assigned arbitrarily (with the natural restriction that they should be located symmetrically with respect to the real axis), provided that the number of gain changes is not less than the system's controllability index. Linearized models of aircraft are obtained at 10 different flight conditions and the controller is designed for controlling the longitudinal dynamics of aircraft using periodic output feedback. The family of 8 plants, representing the longitudinal dynamic, is also simultaneously stabilized. The controller consisted solely of gain elements and did not include a dynamical system, such as an observer, hence it is easier to implement on line.","PeriodicalId":405648,"journal":{"name":"Proceedings of IEEE International Conference on Industrial Technology 2000 (IEEE Cat.
