The proposed part representation method can easily handle parts and raw materials with widely varying geometrical shape by using the part decomposition technique. This considerably reduces the amount of processed data and consequently the run time of the computer. The introduced part decomposition method in the research is a computer-aided approach by using the quadtree encoding. The adopted nesting routine is a global layout process which consists of two states: the initial layout, where a reasonably fine part layout is obtained by the SOAL (self-organization assisted layout) algorithm, and the layout improvement, where the final layout is obtained by the SA (simulated annealing) algorithm.","PeriodicalId":404447,"journal":{"name":"Proceedings of the IECON'97 23rd International Conference on Industrial Electronics, Control, and Instrumentation (Cat.

A conventional fixed-gain linear proportional-integral (PI) controller fails to provide satisfactory transient performance under varying operating conditions. In the proposed gain-scheduled scheme, the proportional and integral gains are allowed to vary within a pre-determined range and therefore alleviates the problems faced by the fixed-gain PI controller. The performance of the proposed scheme has been studied extensively through digital simulation studies for speed control application. Simulation results obtained so far show improvements in transient as well as steady-state responses over conventional fixed-gain PI controller.","PeriodicalId":404447,"journal":{"name":"Proceedings of the IECON'97 23rd International Conference on Industrial Electronics, Control, and Instrumentation (Cat.

Starting from the Petri net model of the plant, it is possible to make a set of assessments of its performance under various operating conditions. These conditions include the change in the topology of the plant, for example concerning the effect of moving some machines from one cell to another, in order to assess the impact on overall performance. The advantage of the performance evaluation approach the authors propose is evident: the designer can assess the effect of any modification in the topology of the plant before it is actually made, and thus decide in advance whether to introduce it or not. The proposed approach is applied to a real semiconductor plant. Here the transport system, which must deliver the products to the relevant machines, plays an essential role in the performance of the plant. The evaluation of the impact on the overall performance of the topology of the machines the transport system must connect appears very interesting. After a brief description of this plant, the Petri net model and the results obtained through simulation are carefully described. They highlight an increase in performance through suitable changes in the topology of the plant.","PeriodicalId":404447,"journal":{"name":"Proceedings of the IECON'97 23rd International Conference on Industrial Electronics, Control, and Instrumentation (Cat.

In the proposed scheme, a voltage source inverter and its corresponding RLC load-filter are controlled, based on the robust model reference adaptive control (RMRAC). Different to the other presented control strategies, such as dead-beat, one sampling ahead preview (OSAP) and adaptive repetitive controller, this scheme is able to compensate unfavorable errors, switching cyclic fluctuating loads and also unmodeled dynamics loads. An on-line adaptive learning algorithm is described which guarantees steady-state controller stability. The principles, stability, robustness, and special features of the control scheme are discussed and the UPS system is presented. Experimental results are presented to verify the feasibility and performance of the proposed approach.","PeriodicalId":404447,"journal":{"name":"Proceedings of the IECON'97 23rd International Conference on Industrial Electronics, Control, and Instrumentation (Cat.

In addition to reducing the stresses in the switch, providing soft transitions in its turn-off voltage and turn-on current, it transfers the entered stored in the snubber capacitor to the load. This is achieved by using a coupled inductor mounted on the main inductor of the power converter, which resets the capacitor voltage at each switching period. Design equations, as well as experimental results, are presented, showing the high efficiency of the boost power converter by using the proposed snubber.","PeriodicalId":404447,"journal":{"name":"Proceedings of the IECON'97 23rd International Conference on Industrial Electronics, Control, and Instrumentation (Cat.

The strategy has featured direct control of a stator flux vector and an output torque instead of the conventional current control technique which had been employed in the field-oriented control, and has given a systematic solution to improve the operating characteristics of not only the motor but also of the PWM inverter. In this paper, looking back upon the fruitful past decade and looking at the present state of the strategy, several key techniques are reviewed. One of the techniques is improvement of the basic performance which was enabled by means of a double-parallel PWM inverter, and has made ultimately quick torque response possible. Another technique is relevant to robust control, which makes the system insensitive to both stator and rotor resistance. Also, the latest technique, which contributes to enhance system performance further, is also referred to.","PeriodicalId":404447,"journal":{"name":"Proceedings of the IECON'97 23rd International Conference on Industrial Electronics, Control, and Instrumentation (Cat.
