In order to have a real-time 3-D imaging of the attitude motion simulator model and to design a multiple views interface in the display and control software of the attitude motion simulator, Firstly, 3D Model of the attitude motion simulator model has been transformed to STL file; Secondly, the functions on the VC++6.0 platform have been written to read the STL file, and 3-D Image display from STL file has been realized by the programming technique of the triangle mesh renderingin OpenGL.Meanwhile, the real-time synchronization has been realized between the 3-D Imageand real angle of attitude motion simulator model.Finally, in order to meet the demands ofcontrol and display software, a multiview control interface in which a real-time data interchange amongthe multiple views is designed.

In order to realize the high precision tracking control of the vehicular eletro-optical tracking turntable with the car bodys vibration, it is necessary to design a high performance turntable servo system and a set of high precision eletro-optical tracking control scheme. In this paper, a digital servo system is designed, which has the control platform based on PC104 processor, has the torque motor as the actuator, has the gyro as the inertial velocity measurement tool and has the high precision encoder as the position measurement tool. Then, the gyrostabilized double speed loop control algorithm with disturbance observer compensating is designed to realize a good inertial velocity stability performace; and, a set of eletro-optical tracking compound position loop control scheme based on the target-missing quality data processing, the segmented PID control and the acceleration lag compensating control is proposed to enhance the eletro-optical tracking precision. The result shows that the tracking turntable based on the control technology designed in this paper is reliable, responses quickly, has a good speed stability performance and a high eletro-optical tracking precision performance.

To meet the demand for high precision measurements of radar cross section (RCS) in microwave anechoic chamber, the effect of angle repeatability of position servo system in background cancellation technology is analyzed and its error mathematical model is presented. Then a method of high speed synchronization angle measurement based on CPLD is proposed, which improves the precision of synchronization angle measurement in any fixed angle interval. The experiment results show that this method can effectively solve the accuracy of target RCS when rotating.
