International Conference on control, Automation and systems ( ICCAS)

作者： Keigo Watanabe Kensaku Okamura Kouki Tanaka Kiyotaka Izumi Department of Advanced Systems Control Engineering Graduate School of Science and Engineering Saga University Saga Japan Sogo Security Services Company Limited Tokyo Japan

A new control strategy is presented for a VTOL aerial robot with four rotors. A kinematics control law is first derived using Astolfipsilas discontinuous control, after introducing a chained form transformation with one generator and three chains to the original model. This was motivated by the fact that the discontinuous kinematic-model without using a chained form transformation assures only a local stability of the kinematic based control system, instead of guaranteeing a global stability of the control system. Finally, a computer simulation is given to demonstrate the effectiveness of our approach.

Adaptive Neural-based Fault Tolerant control for Nonlinear systems

引用

IFAC Proceedings Volumes 2008年第2期41卷 2595-2600页

作者： M.J. Fuente V. Mateo G.I. Sainz S. Saludes Department of Systems Engineering and Control University of Valladolid Science Faculty. Prado de la Magdalena s/n. 47011 Valladolid. Spain

A neural network based fault tolerant control for unknown nonlinear systems is proposed. The faultless system is controlled by a nonlinear Internal Model controller (IMC), where both the direct and inverse models of the plant are carried out by neural networks. Using the residual signal generated from the fault detection path, an extra neural-network fault compensation loop is introduced. This neural network is a two layer perceptron and the weights and bias are updated on-line by the modified-gradient approach, which tries to minimize the control error induced by the fault. In this context, a fault tolerant control scheme is obtained. This scheme is tested in simulation in a pH plant with good results.

A robotic forceps is controlled by voice instructions in the framework of a fuzzy coach-player system. In the proposed system, we can deal with some fuzziness included in voice instructions and the system is composed of two instruction levels in order to increase the efficiency of voice instructions. One is a local instruction level that uses any action commands directly. The other is a global instruction level that uses a task command. Such a fuzzy coach-player system is applied for the manipulation of a robotic forceps and the effectiveness of the present system is verified through some actual experiments.

The paper presents an ongoing investigation of applying finite state machines (FSM) to drive a meal assistance robot based on electromyogram (EMG) signals. An adapting single-threshold method on EMG power is proposed to recognize different elevation gestures. Predefined control commands are output by FSM based on the extracted EMG features, and used to operate the robot. The performance of control mode is tested in efficiency and comfortableness by both subjective and objective indices. And the high performance of the EMG-control meal assistance robot makes it feasible for users with upper limbs motor disabilities.

Habib Department of Electronics and Computer Science Tokyo University of Science Sanyo-Onoda Japan Research & Development Center Meiho Company Limited Nogata Japan Department of Advanced Systems Control Engineering Graduate School of Science and Engineering Saga University Saga Japan Mechanical Engineering Department School of Sciences and Engineering American University Cairo Cairo Egypt

In this paper, a new desktop NC machine tool with compliance controllability is presented for finishing metallic molds with small curved surface. The NC machine tool consists of three single-axis robots with high position resolution. A tool attached to the tip of the z-axis has a small ball-end shape. Also, the control system of the NC machine tool is composed of a force feedback loop, position feedback loop and position feedforward loop. The force feedback loop controls the polishing force consisting of tool contact force and kinetic friction force. The position feedback loop controls the position in pick feed direction. Further, the position feedforward loop leads the tool tip along cutter location data. It is expected that the NC machine tool delicately removes surface cusps with under about 0.3 mm height on a mold, and finishes the surface with high quality. In order to first confirm the application limit of a conventional industrial robot to a finishing task, we evaluate the backlash that causes the position inaccuracy at the tip of the abrasive tool, through a simple position/force measurement. Through a similar position/force measurement and a surface following control experiment along a lens mold, the basic position/force controllability of the proposed NC machine tool is demonstrated.

2008 IEEE Instrumentation and Measurement Technology Conference (I2MTC 2008), vol.2

作者： Janith Dilantha Maddumapatabendi Akira Kimoto Katsunori Shida Department of Advanced Systems Control Faculty of Engineering Saga University Japan

In this paper, we propose an imaging technique which can create both an ultrasonography and an impedance tomography by using the data collected by only one set of transducers. This enables the identification of two completely different sets of properties of a target by the data collected through the same set of transducers, at the same time. The novelty of the proposed system is, piezoelectric transducers which are generally used for ultrasonography is used for both ultrasonography and impedance tomography. In the experiments conducted, we established an ultrasonic and impedance imaging system of sixteen piezoelectric transducers and measured the propagation time and electrical voltage for imaging. We also demonstrate that this system has the ability to detect changes in concentration or changes in position of the target imaging object.

IEEE International Conference on Industrial Informatics (INDIN)

作者： L.L. Chen T. Sugi S. Shirakawa J.Z. Zou M. Nakamura Department of Automation East China University Of Science And Technology Shanghai China Department of Advanced Systems Control Engineering Saga University Saga Japan National Center of Neurology and Psychiatry Tokyo Japan

Sustained mental work easily causes mental fatigue. Comfortable environments are necessary to be introduced into mental work. It is very practical research to explore the characteristics under progressive mental fatigue and make a suitable work-rest schedule. In this research, a work-rest schedule containing mental calculation task and music relaxation is specially designed to reflect effect of prolonged cognitive work and relaxation factors in mental work environments. An integrated design and evaluation system for human fatigue-relaxation research is proposed, which consisted of subjective evidence (visual analogue scale) and objective evidence (calculation performance and bio-neurological signals especially EEG signals). The results from subjective evidence and objective evidence indicate that a short break of music relaxation (e.g. 15 minutes) in sustained mental work can successfully counteract the accumulation of mental fatigue and improve work efficiency. EEG analysis supports the music function from bio-neurological point of view. Suitable work-rest schedule has widespread application in boarder population and various situations to alleviate the impact of every life and improve life satisfaction.

DECi-hertz Interferometer Gravitational wave Observatory (DECIGO) is the planned Japanese space gravitational wave antenna, aiming to detect gravitational waves from astrophysically and cosmologically significant sources mainly between 0.1 Hz and 10 Hz and thus to open a new window for gravitational wave astronomy and for the universe. DECIGO will consist of three drag-free spacecraft, 1000 km apart from each other, whose relative displacements are measured by a differential Fabry-Perot interferometer. We plan to launch DECIGO in middle of 2020s, after sequence of two precursor satellite missions, DECIGO pathfinder and Pre-DECIGO, for technology demonstration required to realize DECIGO and hopefully for detection of gravitational waves from our galaxy or nearby galaxies. © 2009 IOP Publishing Ltd.

作者： Bei Wang Takenao Sugi Fusae Kawana Xingyu Wang Masatoshi Nakamura Department of Automation East China University of Science and Technology Shanghai China Department of Advanced Systems Control Engineering Saga University Saga Japan Department of Electrical and Electronic Engineering Saga University Saga Japan Department of Clinical Physiology Toranomon Hospital Tokyo Japan

An automatic sleep stage determination system dealing with the sleep data contaminated by artifacts is developed, which is working on an expert knowledge-based multi-valued decision making method. The knowledge database is consisted of probability density functions of parameters for various sleep stages according to the visual inspection by a qualified clinician. The probability density functions are approximated by Cauchy distribution on histograms. Sleep stages are determined automatically according to the maximum value of conditional probability. Due to the infinite variance of Cauchy distribution, the effect of mis-determination caused by artifacts can be abated. The result of automatic sleep stage determination was satisfactory. The presented automatic sleep stage determination can be an assistant tool for clinical practice.

Total hip arthroplasty (THA) is performed to replace all or part of a human hip joint with an artificial joint for patients who have rheumatoid arthritis or osteoarthritis of the hip joint. Although THA might result in postoperative complications of dislocation, wear and/or loose, their mechanisms have not been analyzed enough. We have developed an artificial-hip-joint simulator that can generate the same joint posture and joint contact force as those in daily life motion in order to evaluate the performance of the artificial-hip-joint. Dislocation of the artificial-hip-joint during daily living activities was generated by the simulator in order to analyze its mechanism.
