Mobile Carrier Stable Tracking Platform Monitoring And Control Technology

Stabilization and automatic pointing and tracking platform (FTP) is an important field among the applications of the inertial technology. And because of its broad application foreground, antenna stabilization has become a hotspot of stabilization and automatic FTP. The core of stabilization platform is the attitude measurement and control of the carrier. The traditional stabilization platform bases on platform or strap-down inertial system, uses mechatronics or photoelectronical inertial sensor component. The cost of this kind of platform is usually high and the technology is complex. Thus the technology of carrier attitude measurement and control also becomes the difficulty of the development of stabilization platform. With the aim of developing antenna stabilization system which carries by vehicle, this article's research major in the attitude measurement and control of the antenna stabilization platform, which bases on the micro-mechatronics inertial component. The main content of this article include the research on the stabilization scheme of the antenna stabilization system, the constitute of the model of the antenna serve system and the confirmation and optimization of the control parameter, the utility test of the micro-mechatronic gyro and digital compass, the application research of these sensors in antenna stabilization system, the research of the polarization signal scan and automatic pointing and tracking technology.1.The stabilization scheme of antenna stabilization is the foundation of the development the whole system, and plays important role to the utility of the whole system. Aiming at the lack of existing stabilization schemes, this paper proposes an simple schemes which uses micro-mechatronic gyros. An experiment is also carried through.2.This article constitutes the two-step model of the antenna serve system. The digital PID control technology is adapted and a set of optimized parameters are also brought forward here. These parameters offer reference to the real control.3.The principle of the micro-mechatronic angle rate sensors is discussed in this article. A series of experiment is made to test the utility of these sensors. The way to use these sensors in the antenna stabilization system and to make up of the error is proposed here. The principle of the digital compass module and the factor which affect its accuracy is also discussed in the article. Aiming at the specific using request, this paper proposes the way to reduce the error.4.The algorithm of the coordinate transformation during the initial pointing process of the system is developed in this article. And in view of the restrict of the accuracy of the digital compass itself and the installation error, a maximum scan scheme based on signal intensity isstudied. By this scheme, the initial pointing precision is increased to 0.4?5.The characteristic of the polarization signal is studied here and the corresponding noise process method is proposed. Aiming at the limitation of two-axis stabilization and auto track, the optimized signal tracking scheme is proposed.
