This paper describes an automated self commissioning procedure for voltage referenced voltage fed vector controlled induction motor drives. A method for off-line determination of machine electrical parameters is presented. The measurement of the motor electrical variables at standstill time-domain test is used as an identification procedure base. Experimental results achieved with a 10 HP induction motor drive show good agreement between estimated and nominal electrical parameters. The proposed strategy is compared with other identification mechanisms, previously described in the literature, that have been improved with a proposed off-line current-dependent /spl sigma/L/sub s/ adaptation mechanism to obtain better accuracy. Results show similar behaviour using both identification schemes although the proposed scheme requires simpler tests.

This paper presents a novel training algorithm for fuzzy inference systems. The algorithm combines the Levenberg-Marquardt algorithm with variable structure systems approach. The combination is performed by expressing the parameter update rule in continuous time and application of sliding control method to the gradient based training procedure. In this paper, a fuzzy inference mechanism that can be trained such that the adjustable parameter values are forced to settle down (parameter stabilization) while minimizing an appropriate cost function (cost optimization), is discussed. In the application example, control of a two degrees of freedom direct drive SCARA robotic manipulator is considered. As the controller, a standard fuzzy system architecture is used and the parameter tuning is performed by the proposed algorithm.

To reduce resonance effects in contouring machine tools, feedback regulation has been the conventional approach. Although feedback control might effectively increase the bandwidth or suppress the vibration, it often accompanied by increased actuator efforts and reduced stability margins. In this paper, an integrated approach of command interpolating, notch filtering and feedforward control to compensate for resonance effects is explored. Since the feedback loop of the original system is left unchanged, the proposed scheme poses no threat to the system stability, and excessive control signals can be avoided. Design issues are discussed and simulation results are shown with a comprehensive model of a laser profiling machine.

This paper describes abnormal sound detection in plant equipment. Their target was to detect steam leakages, which is one of the most important indications of power plant failure in its early stages. Fourier analysis, which is a conventional method for the sound processing, cannot detect small abnormal sounds mixed with large normal sounds. The authors focus on the characteristics of adaptive digital filters (ADF), which enhance a small signal in a large background noise, and propose an abnormal sound detection method by comparing the properties between normal and abnormal filters produced by the ADF process. Finally, they show the efficiency of this method by applying it to sounds recorded in a power plant. The results of its application to sound source detection are also reported.

This paper describes the design and development of a fuzzy logic controller for the position control of wheeled mobile robots (WMRs). The WMRs are of the type applied in Micro Robot Soccer Tournament (MIROSOT). To meet the control objective, conventional methods rely on an accurate dynamic model of the open-loop plant, as well as a well-calibrated image system. To alleviate these limitations, we propose the use of fuzzy logic controllers that incorporate expert knowledge in terms of linguistic rules. Simulations and experiments have shown that such a fuzzy controlled WMR can have a better performance than a fine-turned PD-controlled WMR.

In this paper, the authors investigate the properties of the PROFIBUS MAC protocol when operated over error prone links, like wireless links. In order to show that the protocol is very sensible to loss of control frames (e.g. token frames), the authors evaluate three performance measures, using a simulation approach: the mean delay, the mean station outage time and the cumulated outage time, i.e. the fraction of time where a single station is not member of the ring due to loss or error of control frames. The results indicate that the PROFIBUS MAC protocol is not really a good choice for use over error prone links.

This paper proposes an improved integration method to realize single phase power factor correction in continuous conduction mode by adding a ripple compensation network comprised of two resistors to the basic integration control circuitry. This method effectively reduces the total harmonic distortion (THD) in the input current. The proposed method is easy to implement. Theoretical analysis is given in detail. Experimental results demonstrate the validity of the approach. This method is very suitable for IC fabrication.

This paper presents an excitation system for an induction generator. The induction generation used in a small power wind energy system operates with variable frequency, making possible to operate with maximum efficiency for variable wind speed. In order to make the system robust and cheap, the rotor is direct coupled to the generator that is operated at low speed. The inverter switches operate with a sinusoidal PWM strategy which reduces the number of switching by one-third when compared to the conventional PWM method.

SEMATECH developed the CIM framework specification to facilitate the creation of an integrated, common, flexible, modular object model leading to an open, multi-supplier CIM system environment in the semiconductor industry. However: all the equipment must comply with the SEMI SECS/GEM standards to interface with the CIM framework's machine management components. SEMI is developing an object-based equipment model (OBEM) standard to tab full advantage of the CIM framework. With OBEM, the equipment can communicate with the CIM framework directly by method invocation. This work develops OBEM-compliant object-based equipment (OBE) in the MES framework environment, such that this equipment can directly communicate with the a MES framework, without using the SECS/GEM protocol. Therefore, a systematic approach for developing this object-based system using object technology is proposed. The unified modeling language (UML) is adopted as the major tool for analyzing and developing the target system. A SECS/GEM adapter is also added on the OBE to enable the OBE to be integrated with a legacy factory which can only use SECS/GEM standards. A die bonder is used as example equipment for development demonstrations.
