This paper describes property evaluation and clustering of sensor data that depends on different gas types and their concentrations. The application subject is to find gas specific information by a multidimensional feature set to give qualitative and quantitative statements. This is investigated by different clustering methods, the fuzzy-c-means algorithm and its derivatives and neural networks. The resulting patterns will be deployed as recognition field for gas detection, that takes recalibration mechanisms into consideration.

Novel contour extraction algorithm for a moving target based on image fusion

Guangdianzi Jiguang/Journal of Optoelectronics Laser 2005年第8期16卷 973-977页

作者： Zhao, Peng Cao, Jun Pu, Zhao-Bang Zhang, Tian-Wen Department of Automation Measurement and Control Harbin Institute of Technology Harbin 150001 China Mechanic and Electronic Institute Northeast Forestry University Harbin 150040 China Department of Computer Science and Engineering Harbin Institute of Technology Harbin 150001 China

A contour extraction algorithm for a moving target is proposed. This algorithm consists of three steps. Firstly, motion segmentation is applied respectively to infrared and visible image sequences to get an initial contour of a moving target. Secondly, a dynamic contour is applied to make the initial contour converge to the target's contour. Finally, two novel image fusions are applied. The first fusion minimizes L2 norm's square of the difference of control point vectors in two modal images without image registration. The second fusion is realized by the modified differential coupling with image registration. Contrasting detection experiments indicate the second fusion is better. Meanwhile, a fast iteration algorithm of dynamic contour based on the Newmark method is devised. A contrasting experiment indicates its iteration time for stable convergence decreases by 21.01% compared with the Wilson-θ method.

IEEE Conference on Decision and control

作者： Lei Ma K. Schilling C. Schmid Department of Computer Science VII Universität WÜrzburg Wurzburg Germany Institute of Automation and Computer Control Ruhr Universität Bochum Bochum Germany

This paper is concerned with the adaptive slidingmode control of a class of nonlinear systems in nonlinear parametric-pure-feedback form with mismatched uncertainties. Backstepping design procedure is applied, which leads to a new adaptive sliding-mode control. Gaussian radial-basis-function networks are used to approximate the unknown system dynamics. A new growing scheme of the Gaussian networks is proposed. The networks start with a loose structure in order to reduce the computational effort. More nodes are added to the networks progressively in order to improve the transient behaviour. With ideal sliding mode, asymptotic stability is reached. The performance of the control scheme is illustrated by simulation studies.

Dongnan Daxue Xuebao (Ziran Kexue Ban)/Journal of Southeast University (Natural science Edition) 2005年第SUPPL.期35卷 67-70页

作者： Yang, Hongyong Zhang, Fuzeng Lin, Xiangze Zong, Guangdeng Department of Computer Science and Technology Yantai Normal College Yantai 264025 China Department of Automatic Control Engineering Southeast University Nanjing 210096 China Institute of Automation Qufu Normal University Qufu 273165 China

Internet congestion control system is considered as a closed-loop feedback system with time-delay. A proportional-integral-differential (PID) controller is then established as active queue management (AQM) scheme to adjust the congestion marked possibility at the links in Internet, whose parameters is auto-tuned by applying the minimization of an integral criterion for adapting the change of the network system. The simulations show that the new AQM scheme can control the size of the queue in the buffer to an expected length and has the robustness for the loading perturbation and the parameter change in the network.

In this paper, we aim at developing a System-on-Chip, SoC, which can capture image as well as produce vehicle lane map at the same time. We adopt Peak-Finding based lane detection algorithm that can achieve high recognition rate about 96% even under various weather conditions. The features of the proposed SoC are a single low-cost and compact chip which implements the lane detection algorithm with mixed signal mode CMOS image sensor. Therefore, it can be easily used in thousands of consumer electronics for intelligent automobile applications. © IEEE.

作者： E.T. Silva M.A. Wehrmeister L.B. Becker F.R. Wagner C.E. Pereira Computer Science Institute Federal University of Rio Grande do Sul Brazil Automation and Control Systems Department Federal University of Santa Catarina Brazil Electrical Engineering Department Federal University of Rio Grande do Sul Brazil

This paper discusses a design flow for multithread object-oriented real-time applications, running on top of an embedded, platform-based, customizable Java processor, which is prototyped using affordable FPGAs. The proposed approach enforces design space exploration activities, taking into account aspects like temporal behavior, memory footprint, and power/energy consumption. A case study containing a task scheduler implementation as both software and hardware modules is presented. While both implementations are compatible with the developed program from an interface point of view, they lead to different timing and footprint requirements. Their evaluation in terms of memory occupation and number of FPGA logic cells is presented.

The growing complexity of today's embedded real-time systems demands new methods and tools in order to manage the problems of design, analysis, integration and validation of complex systems. This paper describes an object-oriented platform-based design process for real-time embedded systems. The proposed approach promotes a smooth transition from high-level UML specification to implementation, which is composed by hardware and software components. The transition from higher to lower abstraction levels is facilitated by the use of an OO realtime API, whose underlying facilities can be optimized according to the application needs and selected platform. An integrated toolset is used to support the intermediate steps of the design process. In order to illustrate the proposed approach and related toolset the design of an embedded real-time automation system for an "intelligent" wheelchair is presented.

The global and local stability of process systems in generalized Lotka-Volterra form is studied in this paper using entropy-like and quadratic Lyapunov function candidates. The global stability check for LV models is performed by solving an LMI for a diagonal positive semi-definite matrix using singular perturbation technique. It is shown that a quadratic Lyapunov function can also be determined by solving linear matrix inequalities (LMIs). In addition, the quadratic stability neighborhood is convex in the space of the quasi-monomials and can be estimated by computing its comer points using LMIs. Furthermore, it is proved that quadratic stability with a diagonal weighting matrix enables to construct adissipative-Hamiltonian description of the system. The developed methods are illustrated on the model of a continuously stirred tank reactor with a nonlinear reaction system. Copyright © 2004 IFAC.

Intelligent space (iSpace) is a space (room, corridor, or street), which has distributed sensory intelligence and it is equipped with mobile agents. In this paper new concept of the iSpace to connect distant places, over packet switched network is introduced. Experimental iSpace of Hashimoto Lab, University of Tokyo, Japan and Advanced Diagnosis automation and control Lab, North Carolina State University, USA is connected to form an inter-continental intelligent space. Conventionally, in order to control an application over a data network, a specified control of teleoperation algorithm is usually required for controller design to compensate network delay effects. Therefore an existing controller has to be redesigned or replaced by a new controller system. This replacement process is usually costly, inconvenient, and time-consuming. In this paper, a novel methodology to enable existing controllers for networked control and teleoperation by middleware is introduced. Mobile agent located in Japan is controlled by tracking controller located in USA to show the effectiveness of the middleware methodology.
