The demand for integration of manufacturing process model into product model is taken into account. In this important field of application, a need has been emerged for description of all process variants in a single model and for generic model descriptions for a cluster of manufacturing tasks. The authors have developed a four levelled generic process model. Entities of this model are easy to understand for production engineers that are represented by Petri net. In the paper, first the importance of the manufacturing process model and its interconnections with other product related models are emphasized. Following this, the manufacturing process model is described and the method of its application is outlined. Next, creating and evaluation of the model are explained. Finally, features of the model and the modeling activity are concluded.","PeriodicalId":404447,"journal":{"name":"Proceedings of the IECON'97 23rd International Conference on Industrial Electronics, Control, and Instrumentation (Cat.

However, a clear and simple design method satisfying specifications for robust stability, influence of measurement noise, and relative stability has hardly been proposed. In this paper, we clarify the class of the robust servo system realized by adjusting the order of the disturbance observer and show design of an estimated disturbance feedback by the disturbance observer, which can represent a classical control approach. We apply this strategy to a design of a position servo system and realize the high performance robust servo system using the high order disturbance observer.","PeriodicalId":404447,"journal":{"name":"Proceedings of the IECON'97 23rd International Conference on Industrial Electronics, Control, and Instrumentation (Cat.

A 12-pulse AC-DC power converter is the most widely topology used in different heavy industrial loads because the 5th, 7th, etc. harmonic currents will disappear in the primary side of the power converter transformer under ideal operation conditions. Simultaneously, other terms are produced from the power converter through its transformer, and injected into the distribution system. However no exact analytical method has been proposed to analyze such effects via the new real power definition in the literature. Therefore, in this paper, the authors propose an effective method to solve the above problem. Via the proposed method and statistical theory, a 12-pulse MVA-rating power converter load in a heavy chemical industry is presented to analyze and estimate harmonic losses. These results of harmonic losses can provide available data to enable power engineers to understand power losses and the characteristics of demand-side loads.","PeriodicalId":404447,"journal":{"name":"Proceedings of the IECON'97 23rd International Conference on Industrial Electronics, Control, and Instrumentation (Cat.

The speech signal is compressed using linear prediction analysis and recognized by neural networks. This neural network technique is presented for the task of speech recognition and speaker verification. This technique first uses pattern recognition to identify the speech, then it is used to distinguish each user from all other speakers (impostors). With this method, unknown speech can be accurately classified as user or impostor speech. The approach used is based on the following steps: extraction of spectral features; training of an initial neural network to identify the speech; extraction of LPC-reflection coefficients for each user, training of a secondary neural-network to identify the user; and classification of unknown speech as either user or impostor.","PeriodicalId":404447,"journal":{"name":"Proceedings of the IECON'97 23rd International Conference on Industrial Electronics, Control, and Instrumentation (Cat.

For this control scheme to work, the disturbances must be of known waveform type, such as a step function, ramp function, sinusoidal function, etc. The basic idea of DAC is to model the disturbance, augment its state equations to the system state equations, and then reconstruct the states of this augmented system for use in a controller that minimizes the effects of the disturbance. Disturbance accommodation control is applied to reduce the adverse effects of step, ramp, and sinusoidal disturbances acting on a servo system.","PeriodicalId":404447,"journal":{"name":"Proceedings of the IECON'97 23rd International Conference on Industrial Electronics, Control, and Instrumentation (Cat.
