A dual-arm robotic manipulator needs to maintain its end-effectors' orientations with reference to each other as defined by the task constraints at various locations. To give one example, the task of operating a pair of pliers by rigidly grasping its handles will require that the orientation of the two end-effectors with respect to each other should vary as a function of their respective locations. Due to the wrist joint range limitations, dexterity is very limited and it may not be possible to achieve a desired maneuver along a desired trajectory. We present here a systematic approach to judge the feasibility of such demands and a method to find other reasonable target trajectories or orientations. The approach here is based on simple geometry with little computation load.

Capturing 3-d information using several 2-d images of topological 3-d objects obtained by acquiring the images under varying illumination conditions is a technique which can be employed in manufacturing systems. The paper deals with the tasks of acquiring the images from objects with hybrid reflecting behaviour and algorithms for extracting the 3-d information and gives results obtained for a grinding tool inspection system. © 2004 IEEE.

3-d topography of objects is often obtained only on a qualitative basis by a sequential reconstruction process using segmented images obtained under different illumination conditions. The approach we present in this paper is based on the direct segmentation and topography analysis of a topographic scene using a sequence of images obtained by varying the illumination parameters in a pre-selected format. Thereby a correlation of the grey level variations of the individual pixels with the variations of the illumination parameters is employed to achieve superior segmentation and topographical information. An advantage is that the pipeline of separate operations viz. image fusion, segmentation topographical analysis is reduced to just one direct operation. The method has been successfully applied to determine the topography of grinding surfaces in machining in manufacturing processes. © 2004 IEEE.

作者： D. Henrion V. Kucera A. Molina-Cristobal LAAS CNRS Toulouse France Institute of Information Theory and Automation Academy of Sciences of Czech Republic Prague Czech Republic Faculty of Electrical Engineering Czech Technical University Prague Czech Republic Department of Automatic Control and Systems Engineering University of Sheffield Sheffield UK

Traditionally, when approaching controller design with the Youla-Kucera parametrization of all stabilizing controllers, the denominator of the rational parameter is fixed to a given stable polynomial, and optimization is carried out over the numerator polynomial. In this work, we revisit this design technique, allowing to optimize simultaneously over the numerator and denominator polynomials. Stability of the denominator polynomial, as well as fixed-order controller design with H/sub /spl infin// performance are ensured via the notion of a central polynomial and LMI conditions for polynomial positivity.

IEEE Conference on Decision and control

作者： C.W. Scherer H. Chen F. Allgower Mechanical Engineering Systems and Control Group Delft University of Technnology Delft Netherlands Department of Control Science and Engineering Jilin University Changchun China Institute for Systems Theory Engineering University of Stuttgart Stuttgart Germany

We consider the problem of L/sub 2/-gain disturbance attenuation by state-feedback with hard bounds on the control. We provide a systematic construction of a hybrid dynamic state-feedback controller by convex optimization. As the main features we suggest a scheme to relax or tighten the performance specification in order to obey hard control constraints while still guaranteeing dissipation for the controlled system.

作者： Lively, KA Seman, AJ Kirkpatrick, M KENNETH A. LIVELY graduated from the University of Colorado with a BS in applied mathematics and an MS in mathematics in 1976 and from the Massachusetts Institute of Technology with an MS in electrical engineering and the degree ocean engineer in naval architecture and marine engineering in 1984. He retired from the U.S. Navy in 1989 after 23 years of service. Assignments included electrical officer on the USS Constellation (CV 64) project engineer for the DDG 51 machinery control system (NAVSEA) and DDG 51 Technical Director (NAVSEA). He was vice president of the PDI Division of Bird-Johnson Company from July 1989 to November 1998 where he managed various gas turbine and machinery controls related development projects. He joined Anteon Corporation's Systems Engineering Group as senior controls engineer in December 1998 where he provided technical support to the integrated power systems program (NAVSEA PMS 510) and managed the Office of Naval Research Afloat Laboratory. DR. MARK KIRKPATRICK is currently an independent consultant in human factors and work-load/manning analysis and modeling. He holds a Ph.D. degree in experimental psychology from The Ohio State University and has 34 years of experience in applied human factors. From 1982 through 2000 Dr. Kirkpatrick served as the senior vice president of Carlow International. Prior to joining Carlow in 1982 Dr. Kirkpatrick served as a member of the technical staff at North American Rockwell's Missiles Division and as a project director and vice president for Essex Corporation. His areas of expertise include workload simulation task analysis operator-in-the-loop simulation human performance experimentation statistical analysis and human factors T&E. He has directed and/or participated in human factors projects for the U.S. Navy U.S. Army NASA Department of Transportation the U.S. Nuclear Regulatory Commission and private industry. ANTHONY J. SEMAN III is the technical manager for the reduced ship's crew by virtual presence (RSVP) advanced technology d

Aboard current ships, such as the DDG 51, engineering control and damage control activities are manpower intensive. It is anticipated that, for future combatants, the workload demand arising from operation of systems under conditions of normal steaming and during casualty response will need to be markedly reduced via automated monitoring, autonomous control, and other technology initiatives. Current DDG 51 class ships can be considered as a manpower baseline and under Condition III typical engineering control involves seven to eight watchstanders at manned stations in the Central control Station, the engine rooms and other machinery spaces. In contrast to this manning level, initiatives such as DD 21 and the integrated engineering plant (IEP) envision a partnership between the operator and the automation system, with more and more of the operator's functions being shifted to the automation system as manning levels decrease. This paper describes some human systems integration studies of workload demand reduction and, consequently, manning reduction that can be achieved due to application of several advanced technology concepts. Advanced system concept studies in relation to workload demand are described and reviewed including. Piecemeal applications of diverse automation and remote control technology concepts to selected high driver tasks in current DDG 51 activities. Development of the reduced ship's crew by virtual presence system that will provide automated monitoring and display to operators of machinery health, compartment conditions, and personnel health. The IEP envisions the machinery control system as a provider of resources that are used by various consumers around the ship. Resource needs and consumer priorities are at all times dependent upon the ship's current mission and the availability of equipment pawnbrokers.

This paper proposes the time space MUSIC technique using the chirp pulse signal of a tracking radar. Direction/time of arrival (D/TOA) estimation characteristics are evaluated for the simulated point sources, simulated extended air targets, and the actual extended air targets. It is shown that the proposed technique is enable to highly resolve and precisely estimate D/TOA of the actual targets covered by one radar beam width.
