A Study On The Measurement And Control Technology Of The Attitude Stabilization Platform

Stabilization platform 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. The core of stabilization platform is the attitude measurement and control of the carrier. With the aim of developing'Dong Zhong Tong'system, this article's research major in the attitude measurement and control of the stabilization platform, which bases on the micro-mechatronics inertial component.'Dong Zhong Tong'system uses mechatronics to form closed loop control mould.the mechatronics acquits the attitude change of carrier in inertial space because of the attitude change of carrier.then make the point of antenna unchangeable by using stated control mould.The error is compensated through coning scanning control arithmetic,thus the closed-loop control system is formed , substantially,the feedback of the system is the intension of singal. The main content of this article include the research on the system carriage coupling,the dynamics analyzing of the three axis stabilization platform,the effect in the initial pointing process of the system by the installation error of the digital compass, coning scanning control algotithms at inertial frame and forward–back&feedback control.1.The stabilization scheme of platform is the foundation of the development the whole system, fisrstly, the carriage coupling principle of the two axis stabilization is discussed in this article.Aiming at the limitation of two-axis stabilization, the dynamics analyzing of three-axis stabilization and carriage coupling are researched.2. The principle of the initial pointing is discussed in this article. the effects in the initial pointing process of the system by the installation error of the digital compass is brought forward here, it offers reference to the real control.3. The principle of the coning scanning is discussed in this article. this paper proposes coning scanning control algotithms at inertial frame, proposes a control scheme which first azimuth then pitch controling by comparison between emulation and reality.4. The core problem of the whole system are the control methods. Aiming at the limitation of old system, forward–back&feedback control scheme is proposed, it improves stabilization precision,the whole system has occurs qualitative improve.
