Instantaneous dynamic phasor estimates with Kalman filter

Instantaneous dynamic phasor estimates with Kalman filter

IEEE PES General Meeting, PES 2010

作者： De La O Serna, José Antonio Rodríguez, Johnny PhD Electrical Engineering Program UANL Monterrey Mexico

ISBN: (纸本)9781424483570

The state-transition matrix of the κ-th order Taylor approximation to the dynamic phasor and its first derivatives leads to a plurality of state-space representations to approach the bandpass signal model of a power oscillation. With these truncated signal models, the Kalman filter algorithm can be applied to their state vectors in order to find observers able to estimate the dynamic phasor and its first derivatives. The estimates obtained through this technique are not only instantaneous (no delay) but also synchronous, an important attribute for control applications. Even if the results are in their preliminary stage, they are promising and open the way to a new family of phasor estimators. ©2010 IEEE.

Annual International Conference of the IEEE engineering in Medicine and Biology Society (EMBC)

During medical procedures, such as surgery, a patient's vital signs are typically monitored using a web of wires connected to adhesive electrodes. The large number of wires inhibits the medical team's access to the patient while the adhesive electrodes can detach, fail, or be out-of-stock, causing delays in the procedure. In order to combat these problems, we have developed the SmartPad: a system that displays a patient's electrocardiogram (ECG) signal without adhesive pads, wires, or active intervention from a clinician. The system automatically selects three electrodes from an array of Cu/Ni-fabric based electrodes patterned on a thin pad on which the patient lies. The selected electrodes are used to provide a differential 3-lead measurement of the patient's ECG, which is then transmitted wirelessly and displayed on a laptop computer.

This paper presents evidence that English as a second language (ESL) middle school students can effectively learn engineering concepts through a sequence of one hour, hands-on activities. electrical and mechanical engineering concepts are introduced through an integrated sequence of one hour modules. These cross-disciplinary modular activities include exploring mechanical potential through flowing water, building electric circuits, and using this knowledge to build a model electric car. These engineering-based activities provide a rich source for enhancing academic language skills through speaking and writing in English. Methods for training undergraduate and graduate engineering Teaching Fellows to work effectively with ESL students are provided. The process of creating K-12 engineering-based lessons and activities for publication in the Teachengineering Digital Library, part of the National Science Digital Library, is outlined using the engineering-based curricular unit created in this project. This project was completed by a senior undergraduate student in the Department of Biomedical engineering at Duke University in partial fulfillment of the requirements for the Bachelor of Science in engineering Degree. © American Society for engineering Education, 2007.

Delay and computational complexity reduction on the phasor estimates calculated under power system oscillations is the main objective of this paper. Different approximations to the Raised Cosine (RC) filter lead to a reduction in delay and computational complexity of the phasor estimates. As for finite impulse response (FIR) filters, the minimum-phase implementation of the RC linear-phase FIR filter reduces by a half the delay of the phasor estimates, without introducing significant phase distortion and with shorter transients. This improvement in speed provides faster estimates for real-time monitoring and control applications. On the other hand, infinite impulse response (IIR) filters reduce the computational complexity of the estimates by a factor of ten, but without significant delay reduction, introducing a higher distortion, and with longer transient behavior. This solution could be useful for implementations in which computational complexity is a matter of serious concern. In this way, the paper provides a wide range of solutions for those who need more accurate, faster or simpler estimates. © 2005 IEEE.

Ship design is often multidisciplinary involving several design elements with various types of objectives and constraints (O/C) some easily described as mathematical formulas, others better modeled as descriptive assertions. This paper describes a method based on fuzzy functions and an integrated performance index to model O/C using descriptive assertions to be used with mathematical formulas in optimization. Another issue addressed in this paper concerns the coordination of design elements when sequentially coupled, that is, when one leads the other and the performance of the follower depends greatly on the design of the leader. Based on neuro-fuzzy techniques, the method described here coordinates and optimizes sequentially coupled elements. The two methods are applied to machinery arrangement (MA) and pipe routing (PR). Preliminary models for optimization of MA and PR are described considering convenience, producibility: engine room size, interference and location as factors in the O/C set. Some test results from MA/PR applications are presented and discussed. The methods are generic and can be extended to other elements in ship design. They are mutually independent and may be used separately Two advantages of their use are an improvement in overall performance and a reduction in the need for redesign of elements.

INTERNATIONAL JOURNAL OF MICROWAVE AND MILLIMETER-WAVE COMPUTER-AIDED engineering 1993年第4期3卷 326-339页

作者： DICH, M OSTERGAARD, A GOTHELF, U Electromagnetics Institute Technical University of Denmark Building 348 DK-2800 Lyngby Denmark Allan Ostergaard was born in Denmark on May 10 1963. He received the MScEE degree from the Technical University of Denmark (TUD) in 1987. In 1987 he joined the Electromagnetics Institute at TUD where developed high speed digital circuitry for the Danish Airborne SAR system. In parallel with the above work he began a PhD program in September 1988 at TUD. His research interests are in the field of numerical analysis and design of radiating printed structures. He is currently working at ESTEC The Netherlands. Ulrich V. Gothelf was born in Denmark on November 21 1965. He received the MScEE degree from the Technical University in Denmark in March 1991. He is currently pursuing a PhD degree in Electrical Engineering at Electromagnetics Institute at the Technical University in Denmark. His main research interest is numerical calculation on microstrip antennas.

A network model for an aperture coupled microstrip patch is developed. The derivation of the topology of the network model is based on electromagnetic arguments. The values of the components in the network model are found by optimization using input reflection coefficient data computed from a method of moments model. The topology of the network model is described together with a procedure for the determination of the values of its components. After the determination of the values of the components, the network model can be used in a CAD program for a large range of mechanical dimensions, without the need of additional method of moments calculations.

The use of an electromagnetic analysis of 3-D planar structures is described with respect to the educational requirements of students from the college freshman level through the graduate level. The analysis is intended primarily for microwave use; however, there is also significant potential interest from the student of high speed digital design. The analysis is used for passive planar circuits with any number of layers. The third dimension is represented by vias. A mature graphical user interface is provided allowing rapid capture of structure geometry, color visualization, and animation of the resulting current distributions. The software is also explicitly designed to work in conjunction with popular circuit theory based microwave software and with SPICE.
