IEEE International Workshop on Robot and Human Communication (ROMAN)

作者： T. Salter F. Michaud K. Dautenhahn D. Letourneau S.

For meaningful interaction between a robot and a human, an autonomous robot must recognize whether the experienced situation is created by people or by the environment. Using only proprioceptive data from a mobile robotic platform, we discover that it is possible to distinguish sensory data patterns involving interaction. These patterns are obtained whilst navigating varying environments, both human populated and unpopulated. The paper reports the initial set of trials using Roball, a spherical mobile robot. Also described is the experimental methodology currently followed to validate the hypothesis that child interaction can be perceived directly from navigation sensors onboard a robotic platform.

This paper outlines major challenges that we are facing in interfacing a human user with objects in the nanoworld via a haptic interface. After a review of prior efforts at haptically-enabled nanomanipulation systems, we present the current state of our nanomanipulator system. We then discuss current research issues including the direct-Z mode, force modeling, data transfer rates and the stability of the haptic interface. Results of nanomanipulation of single-walled carbon nanotubes are presented. It is our hope that the insight gained by the human user of a haptic interface to SPM leads to scanning algorithms that can automatically adjust the SPM parameters based on the properties of the nanosample and the substrate under investigation. © 2005 IEEE.

IEEE International Conference on Electric Machines and Drives (IEMDC)

作者： L. Parsa N. Kim H.A. Toliyat Department of Electrical Computer and Systems Engineering Rensselaer Polytechnic Institute Troy NY USA Department of Electrical Engineering Advanced Electric Machines & Power Electronics Laboratory Texas A and M University College Station TX USA

This paper investigates the field weakening operation of a five-phase permanent magnet motor. The proposed motor has concentrated windings such that the produced back-EMF is almost trapezoidal. The motor is supplied with the combined sinusoidal plus third harmonic of currents. This motor, while generating the same average torque as an equivalent permanent magnet brushless DC motor, overcomes its disadvantages. It is shown that torque producing and flux producing components of current for this motor can be decoupled by using multiple reference frame transformation. Therefore, vector control is easily applicable to the motor. Field weakening algorithm is derived and implemented. This motor benefits from high torque density of a BLDC motor below the rated speed and controllability of PMSM above the rated speed and during the field weakening region. Simulation and experimental results are provided to prove the validity of the superior performance of this drive

IEEE Symposium on Radio Frequency Integrated Circuits (RFIC)

This work presents experimental characterization of intermodulation linearity of CMOS transistors from a 0.13 /spl mu/m process. The IIP3 in the saturation region is shown to increase with V/sub ds/, even though g/sub m/ saturates. The IIP3 in strong inversion is found to be higher than the IIP3 at the well known linearity sweet spot near the threshold voltage. Longer channel transistors and thick oxide transistors are found to have linearity advantages. The results provide useful guidelines for optimal biasing and device selection in RFIC design.

Conference Record of the IEEE Industry Applications Society Annual Meeting (IAS)

作者： O. Ojo Gan Dong Department of Electrical and Computer Engineering/Center for Energy Systems Researc Laboratory for Electric Machines and Power Electronics Tennessee Technological University Cookeville TN USA

Using an expanded reference frame transformation expressed in the complex-variable form, the possibilities offered by multi-phase converters, using carrier-based, sine-triangle pulse-width modulation to generate voltages of different frequencies to actuate multi-phase electric machines are set forth. The generalized expressions for the modulation signals, including the neutral voltage component to be compared with the high frequency triangle waveform to synthesize reference voltages for both five and six-phase converter-electric machines are determined. How the inclusion of the neutral voltage affects the modulation signals and the voltage gain and waveform quality is discussed. Some experimental results of synthesized five phase converter voltage waveforms are provided to validate the voltage waveform synthesis using carrier-based generalized (dis)continuous pulse-width modulation for operation in both the under and over- modulation regimes.

Conference Record of the IEEE Industry Applications Society Annual Meeting (IAS)

作者： Z. Wu O. Ojo Department of Electrical and Computer Engineering Center for Energy Systems Research Laboratory for Electric Machines and Power Electronics Tennessee Technological University Cookeville TN USA

A new current controller structure for the three-phase boost rectifier, using actual phase currents achieving both controllable input power factor and constant DC voltage under asymmetrical source voltages and/or unequal line impedances, is presented in this paper. All the control variables in the new scheme are AC signals instead of the DC signals used in the industry standard synchronous reference frame controllers, eliminating the synchronous reference transformations of the currents, voltages and the hardware (phase lock loop) or software required for voltage phase angle measurement. Under asymmetrical source voltages, a generalized discontinuous PWM method is also developed which can also reduce the device switching loss of the rectifier. An attraction of this controller strategy lies in the ability to transparently achieve leading, lagging and unity power factor operation with regulated DC voltage. With a digital signal processor (DSP), the proposed control algorithm has been experimentally implemented; the experimental results demonstrate their significant effectiveness.

Enterprise integration is significant for the enforcement of novel business models in an enterprise/industry. The great heterogeneity of systems/applications in the enterprise environment requires the introduction of interoperability aspects in order to resolve integration problems in a flexible and dynamic way. Our approach introduces an advanced enterprise semantic model representing both enterprise structure and available services, through the use of ontologies. The model is associated by a specific architecture that uses the above model in combination with state-of-the-art technologies such as Web services and workflows
