In-situ experiments conducted within a transmission electron microscope provide the operator a unique opportunity to directly observe microstructural phenomena, such as phase transformations and dislocation-precipitate interactions, “as they happen”. However, in-situ experiments usually require a tremendous amount of experimental preparation beforehand, as well as, during the actual experiment. In most cases the researcher must operate and control several pieces of equipment simultaneously. For example, in in-situ deformation experiments, the researcher may have to not only operate the TEM, but also control the straining holder and possibly some recording system such as a video tape machine. When it comes to in-situ fatigue deformation, the experiments became even more complicated with having to control numerous loading cycles while following the slow crack growth. In this paper we will describe a new method for conducting in-situ fatigue experiments using a camputer-controlled tensile straining holder.The tensile straining holder used with computer-control system was manufactured by Philips for the Philips 300 series microscopes. It was necessary to modify the specimen stage area of this holder to work in the Philips 400 series microscopes because the distance between the optic axis and holder airlock is different than in the Philips 300 series microscopes. However, the program and interfacing can easily be modified to work with any goniometer type straining holder which uses a penrmanent magnet motor.

Wind power is an important direction of new energy, which has no pollution, no consuming fossil fuels, and no producing waste, which is widely used at this stage of clean energy. The small stand alone wind power has been paid more and more attention due to its low cost, flexible installation, strong adaptability. This paper introduces the mechanical and electrical structure, which are used in KW level stand alone mode wind turbine automatically track and yaw system. The motion rules and control strategies of the tracking and yaw system are discussed and then the control program flow is provided. The PIC16F873 chip is used as controller for this part in this system. It can fully meet the design requirements, which will reduce costs and increase the system's control ability. This system can automatically track and yaw, according to the wind direction and wind power.

A remotely controlled energy saving combustion control system is developed in this paper. The system includes three parts: upper computer, communication program between upper and lower computer, lower computer control program. Friendly human-machine interface is designed by Labview, which realizes the remote control of PLC; With Visual C, a standard dynamic link library is designed and debugged, by which the serial communication between PC and PLC can be realized; According to the scheme of air-fuel ratio, the control programs are achieved by PLC, which realizes energy saving combustion. The results of experiment in PLC experimental platform shows that the PC can effectively control the PLC .The scheme of air-fuel ratio is similar with the actual situation.

The article explains adaptation of control system for 3D printing device with the use of hot gas powder sintering. The work especially focuses on the use of special powder sintering, where the properties of powder material are unstable, or the printing process has to adapt the change of material volume during printing process. The main principles or main peculiarities of this system are explained, where positioning system is reacting on the material properties by algorithms creating change of control program flow of printing system generated from CAM processors.

Introduced the MCU STM8S105C4’s basic framework,main function modules and corresponding technical parameters.Based on this MCU, With the crankshaft signal and camshaft signal, the throttle valve position signal, intake manifold pressure signal, and other signals for the treatment plan,the injection control and ignition control,we developed a corresponding control program flow charts and software implementation,to make sure the control of the four-cylinder gasoline engine’s operation correct. Simulation results show that,the design of the control system reach the expected goals,that makes the gasoline engine start and running steadily.

Biaxial control systems for generating predetermined paths under load disturbances, such as encountered in NC and CNC systems for machine tools, are conventionally designed such that the control of each axis is independent of the other. The present paper is concerned with providing cross-couplings for biaxial control systems, whereby an error in either axis affects the control loops of both axes. An algorithm for a cross-coupled control system is presented, and the performance of the cross-coupled system is mathematically analyzed and compared with the conventional CNC system having individual axis control. It is shown that cross-coupling between axes improves the contour accuracy while the velocity response of each axis is only slightly reduced. Although the proposed cross-coupled system requires additional hardware for implementation with an NC system, operation with a CNC-based system requires only software modifications to the system control program.

The purposes of this study are: (1) to determine the characteristics of academic administrative (2) to know the description of academic and administrative services and the student resistances. The study is a descriptive qualitative. It is conducted at the Computer Control Engineering Program of Polytechnic Madiun. The respondents in this study are the Chairman, staff, and students of Computer Control Engineering Program. The main data collection tools by means of interviews and documentation. It was developed by the researcher himself and validity tested by triangulation techniques. The results of this study concluded: 1) control program engineering studies led by the chief together with the secretary program, and assisted by the administrative staff. The academic administrations are student planning card, attendance list, class scheduling, semester reporting, the final semester result reporting, and final project schedule, 2) generally the academic administrative services do not fulfill the students satisfactory, such as administrative room less extensive, administrative officer less responsive in providing some services and not in line with a predetermined schedule, but the level of student resistance remains high.
