PID control, resonance ratio control, H/sup /spl infin// control, and etc. have been applied to the two-mass systems. Conventional controllers that use a disturbance observer for two-inertia systems are adopted. A systematic parameter design method for the systems is proposed, where a load variation, Coulomb friction, and fast and precise control are considered. For limit cycle due to friction, a suppression condition of limit cycle is derived by an analysis using a describing function method. For load variation, robust stability for time varying system with structured uncertainty is guaranteed by the quadratic stability. Moreover, nominal performance is improved by maximizing the smallest eigen value of control system under the above restrictions. Effectiveness is confirmed by some simulations and experiments.","PeriodicalId":345608,"journal":{"name":"IECON'01. 27th Annual Conference of the IEEE Industrial Electronics Society (Cat.

Every object in the stadium is given a working layer which is decomposed into a fixed number of small areas. We propose to assign values to different small areas of the layer according to the object's movement. The final path is obtained by combining the small areas of the layers and getting the path with the smallest values. Since the host computer uses only a simple equation to calculate the value of each small area, this algorithm requires only a low computing power, and the speed of path generation is very fast. A simulation program was developed to test the algorithm's performance.","PeriodicalId":345608,"journal":{"name":"IECON'01. 27th Annual Conference of the IEEE Industrial Electronics Society (Cat.

These operations have some difficulty because it requires the unnatural hands manipulations under the microscopic images. So the productivity of those operations is not high. To solve these problems, a 3-D software camera system has been introduced. The system consists of two subsystems those are the 3-D entire shape model with texture extraction system and the stereo image generation system. Here, the method of 3-D model extraction system using mufti-directional camera and its calibration system are introduced, then the system has been introduced to the bio-production system.

The control system employs a preload relay (P_Relay) in series with a PID controller. The P_Relay ensures a high gain to yield a robust performance. However, it also incurs a chattering phenomenon. In this paper, instead of viewing the chattering as an undesirable yet inevitable feature, we use it as a naturally occurring signal for tuning and re-tuning the PID controller as the operating regime digresses. No other explicit input signal is required. Once the PID controller is tuned for a particular operating point, the relay may be disabled and chattering ceases correspondingly. However, it is invoked when there is a change in set-point to another operating regime. In this way, the approach is also applicable to time-varying systems as the PID tuning can be continuous, based on the latest set of chattering characteristics. Simulation results for the level control of fluid in a spherical tank using the scheme are also presented.","PeriodicalId":345608,"journal":{"name":"IECON'01. 27th Annual Conference of the IEEE Industrial Electronics Society (Cat.

This algorithm always observes whether a vehicle is inside the safety limit, and starts controlling the vehicle in the place of the human driver just before going into the dangerous zone where even the system cannot avoid collision. The inputs to the vehicle are the accelerator, the brakes and the steering wheel. The system controls the vehicle by three inputs. The vehicles communicate the three state data, the speed, the position of the coordinates and the direction, with each other. The algorithm derives the best movement to avoid a collision without control data of the other vehicle. In the end, the vehicles avoid collision at the limit of the safety distance and time. In this paper, we give explanations of the algorithm process, and inspection results with a simulator.","PeriodicalId":345608,"journal":{"name":"IECON'01. 27th Annual Conference of the IEEE Industrial Electronics Society (Cat.

Moreover, the newly designed grey feedback linearization control system is implemented for an indirect field-oriented induction servo motor drive to track periodic speed commands. In the proposed control system, a grey uncertainty predictor is designed to adjust the lumped uncertainty existing in the induction servo motor drive into a feedback linearization control law on line. In addition, the effectiveness of the proposed control scheme is verified by both the simulated and experimental results. With the proposed control system, the controlled induction servo motor drive possesses the advantages of good tracking control performance and robustness to uncertainties.","PeriodicalId":345608,"journal":{"name":"IECON'01. 27th Annual Conference of the IEEE Industrial Electronics Society (Cat.
