Semi-physical simulation of attitude control system is the more synthetically test and verify for designing of small satellite control system. It is an important means of small satellite development. However  the results of current semi-physical simulation system have a lot of non-intuitive. Compare with the actual environment  the simulation environment still has striking disparity. So the shortcomings affect precision of simulation. Based on the virtual display technology  the group semi-physical simulation system has been constructed for attitude control of small satellite due to the combination with xPC real-time environment  the simulation computer  high-precision single-axis air-bearing turntable  reaction wheel  air thrust device  fiber gyroscopes  sensors synchronizer  power subsystem and wireless devices virtual display computer etc. Semi-physical simulation achieved the visual simulation in orbit and tracked new information of virtual environment of space into real-time simulation computer. Simulation results show that the simulation system for real-time attitude and orbit position of small satellite semi-physical simulation has an excellent display effect. At the same time  Real-time transfuse of orbit information provides a more accurate space environment simulation. The simulation system of small satellite attitude control to design and evaluate the more direct and convenient. (2012) Trans Tech Publications  Switzerland.

The development of intelligent system which accorded with human cognitive mechanism will exert a profound influence on national defense  economy  education  culture and etc. A computer simulation method according with cognitive mechanism of human vision was proposed on the basis of Structural Decomposition Theory. Many basic shape feature information tables of similar object from different side can determine a kind of object uniquely. System weighted basic shape features in two different information tables by membership degree and then calculated similarity. The identifying object which had the maximum similarity with it in system was what we needed. The system used 83 pictures of 6 kinds of objects with different side for training and testing. The experiment results demonstrated  task of basic shape extraction  object recognition and others can be completed effectively with the method in paper. The method in paper can be a new attempt on computer simulation method according with cognitive mechanism of human vision from cognitive field. 2010 Crown Copyright.

The common bus on bus control is RS232. With the development of field bus technology  field bus technology is widely used in data recorder. How to real time record the data of field bus in the experiment and provide the test data for process reconstruction is a very important problem. This paper introduces a kind of data acquisition and storage based on field bus. Its core design is C8051F040 microprocessor and SJA1000  a widely used field bus controller. This paper presents the basic constitution of this field bus data recorder and set forth its hardware and software. This field bus data recorder field bus real-time gathers the information and storage data on the CF card. The result of the experiment shows the system is highly reliable for data acquisition and storage  which should have abroad application prospect for data record experiment. 2010 IEEE.
