This paper describes an effective distributed collaborative design frame based on UG software for the 3D-CAD design. It develops quadratic exploitation based on Unigraphics software through UG/Open API and TCP/IP protocol, which realizes communication with distributed computers by Winsock programming. Each operation has its own corresponding instruction, which we named it operation map. When someone in cooperative net have forwardly modified the model, the corresponding instruction be transmitted to the other computers, so the model in any other computers can be automatically modified , which makes the real-time distributed collaborative design into reality. © 2007 IEEE.

The well-known Generalized Champagne Problem on simultaneous stabilization of linear systems is solved by using complex analysis and Blonders technique. We give a complete answer to the open problem proposed by Patel et al., which automatically includes the solution to the original Champagne Problem. Based on the recent development in automated inequality-type theorem proving, a new stabilizing controller design method is established. Our numerical examples significantly improve the relevant results in the literature.

Mating a pair of electric connectors is one of the most important steps in a robotic wiring harness assembly system, which can be modeled by static piecewise affine (PWA) systems. To design a fault detection system for this application, a set-membership approach for static PWA systems is proposed, in which parallelotopic approximation of feasible parameter sets (FPS) is adopted. An online algorithm is obtained to estimate bounds of uncertain transition points of the PWA model. Based on the estimation, a robust online fault detection algorithm is proposed. The effectiveness of these methods is finally confirmed through experiments.

Annual Conference of Industrial Electronics Society

作者： Jian Huang Toshio Fukuda Takayuki Matsuno Department of Control Science & Engineering Huazhong University of Science and Technology Wuhan Hubei China Department of Micro System Engineering University of Nagoya Nagoya Japan Department of Intelligent System Design Engineering Toyama Prefectural University Imizu Toyama Japan

Mating a pair of electric connectors is one of the most important steps in a robotic wiring harness assembly system. A piecewise linear force model is reported to describe the successful mating process of connectors via elaborate analysis of force during different phases. The corresponding parameter estimation method of this model is also presented by adapting regular least square estimation methods. A typical type of connectors are investigated in this paper. The results can be extended to other types easily. Experiments show that the presented model has good prospects in fault diagnostic tasks.

Beijing Ligong Daxue Xuebao/Transaction of Beijing Institute of technology 2007年第SUPPL. 1期27卷 140-144页

作者： Zhu, Lin Chen, Jie Chen, Wen-Jie Department of Automatic Control School of Information Science and Technology Beijing Institute of Technology Beijing 100081 China Key Laboratory of Complex System Intelligent Control and Decision Beijing Institute of Technology Beijing 100081 China

A new conversion method for fault tree (FT) to binary decision diagram (BDD) was introduced. Firstly, FT was reduced and the reduction rule was proposed, share-node conception was introduced on the basis of FT decomposition, then the rules of connection of component BDD was proposed. Furthermore the route-based BDD reduction rule was proved, with which reduction can be done at the same time with BDD composition, and the route sequence and cut sets can be obtained, while computation and storage is greatly reduced during the process. Finally, the procedure of the transformation is presented. The affectivity effectiveness and practicability is thereby proved.

作者： Liao, Xiao-Zhong Lu, Guo-Hui Liu, Xiang-Dong Department of Automatic Control School of Information Science and Technology Beijing Institute of Technology Beijing 100081 China Key Laboratory of Complex System Intelligent Control and Decision Beijing Institute of Technology Beijing 100081 China

A Backlash neural network model is proposed for the systems with hysteresis nonlinearity. In order to approximate the hysteresis nonlinearity, Backlash-type operators are used as one layer of the neural network. Then, the number of Backlash operators and neurons of hidden layer are gotten through simulation. Compared with the normal BP network, the results show the improvement validity of the proposed Backlash neural network model for describing the hysteresis nonlinearity.

Beijing Ligong Daxue Xuebao/Transaction of Beijing Institute of technology 2007年第SUPPL. 1期27卷 80-84页

作者： Yang, Chen-Guang Cai, Tao Tu, Xu-Yan Department of Automatic Control School of Information Science and Technology Beijing Institute of Technology Beijing 100081 China Key Laboratory of Complex System Intelligent Control and Decision Beijing Institute of Technology Beijing 100081 China

One problem of marriage in honey bees optimization (MBO) is that its complex computation process will limit its applications. The paper proposed an improved marriage honey bees optimization (IMBO). By randomly initializing drones and restricting the condition of iteration, the calculation process becomes easier. The global convergence characteristic of IMBO is also proved based on the Markov chain theory. With different number of nodes, traveling salesman problem(TSP) is used to compare the IMBO with MBO and genetic algorithm(GA). Simulation results show that IMBO has better convergence performance.

Parameters identification from indirect data and its application in the identification of ballistic parameters

引用

Beijing Ligong Daxue Xuebao/Transaction of Beijing Institute of technology 2007年第SUPPL. 1期27卷 118-122页

作者： Chen, Jie Deng, Fang Chen, Wen-Jie Department of Automatic Control School of Information Science and Technology Beijing Institute of Technology Beijing 100081 China Key Laboratory of Complex System Intelligent Control and Decision School of Information Science and Technology Beijing Institute of Technology Beijing 100081 China

Focuses on a method of parameter identification from indirect data, generated by indirect model. The indirect data are preprocessed in order to approximate the direct data generated by original model. Parameters of the original model are identified from the approximate direct data. This method is employed to establish ballistic mathematical model of projectile based on firing table data. A ballistic integrated coefficient is proposed and identified by parameter identification method in order to establish ballistic mathematical model. The data used in identification are approximated by firing table data. Computation showed that the method was more precise than the simple table lookup method. Moreover, the method is a low-cost way to identify parameters and establish ballistic models.

It has been found that some huge overshoot in the sense of sup-norm may be observed when typical iterative learning control (ILC) algorithms are applied to LTI systems, even though monotone convergence in the sense of λ-norm is guaranteed. In this paper, a new ILC algorithm with adjustment of learning interval is proposed to resolve such an undesirable phenomenon, and it is shown that the output error can be monotonically converged to zero in the sense of sup-norm when the proposed ILC algorithm is applied. A numerical example is given to show the effectiveness of the proposed algorithm.

The time series of wind power generating capacity were examined by nonlinear dynamical methods, in order to identify chaos characteristic from its random-like waveform. The analysis of modeling with low dimensions nonlinear dynamics indicated that time series of wind power generation capacity have chaos characteristic, and wind power generating capacity can be predicted in short time.
