Currently, There are a lot of clustering algorithms in data mining areas, at the same time the new algorithms are emerging more and more. However, each algorithm in the existing mining tools is designed independently that based on their respective mind. After analyzing a large number of clustering algorithms, a conclusion is that some algorithms are designed similarly, some algorithms inherit from others. Therefore, after having summarized the design philosophy of the existing algorithms, found the correlation between them, then realizes the modular of algorithm features with the help of the object-oriented design. It is significant to increase the versatility of the code, and enhance code maintainability and future updates and maintenance of mining tools.

Is Traditional integral order PID control is the method,which is used most widely in the industrial process control. Fractional order PI λ D μ control is the promotion and development of traditional PID control. The fractional calculus theory and basic concept of fractional order PI λ D μ control are introduced in this article, and a new parameters installation method of fractional order PI λ D μ controller is brought forward. This method resolves mainly the design problem of fractional order PI λ D μ controller. Thus the control model of fractional order PI λ D μ controller is obtained. The second-order industry object is taken as the example. The simulation research of fractional order PI λ D μ controller and that of integral order PID control are done separately. The simulation result indicates that the improved fractional order PI λ D μ controller could improve the quality of second-order object, and has better control effect.

A nonlinear model of the rolling mill automatic position control system is derived based on analyzing the friction between roll and metal plate、the flexibility and the roll eccentricity force. The nonlinear characteristic of the automatic position control(APC) system is analysed. The result shows the APC system has chaotic characteristics. Aim at the characteristics of the APC system,such as nonlinear and variable parameter,a robust controller of the APC system is designed based on active disturbance rejection control(ADRC) technology. The simulation results show that the ADRC controller has very strong robustness to the system chaos and the large load disturbance, and rapid and smooth control process and high steady precise performances can be implemented.

Based on software Ansys, the stress distribution of hydraulic pipe wall can be obtained by finite element analysis. The maximum von Mises stress on certain type of aircraft's hydraulic pipe wall which is easily extracted from the results of POST1 is taken as random output variable, and hydraulic pipe sizes and material properties are regarded as random input variables. Then the reliability and sensitivity of maximum von Mises stress in the model can be analyzed and studied when mathematical models of a hydraulic pipe reliability analysis is established.

In this paper, a distributed data mining tool that suitable for distributed and isomeric database environment of intelligent control system by borrowing ideas from architecture of grid is introduced. It can also perform incremental data mining based on history mining result. This tool makes full use of metadata of each kind of resources. The resources associated in the data mining are all packed into form of web service, which is give a description by respective attribute document of the XML format. SOAP takes charge of the communication between the separated parts of the whole data mining process.
