静电陀螺稳定平台的研究

静电陀 螺稳定平台是我国静电陀螺首次在航海上的应用研究项目,其主要特点是采用 静电陀螺摆作为水平敏感元件,能在单个陀螺上通过电参数的调节使之满足无 干扰的Schuler条件。该平台主要由下列部分组成:静电陀螺摆及其控制线路;水平平台控制回路;陀螺摆径向阻尼回路以及纵横摇角度输出装置。本文主 要介绍平台原理、结构、误差分析、静电陀螺摆及其控制线路原理,以及平 台精度的室内测试和海上试验。

ON THE STABILIZING OF PLATFORM WITH ELECTROSTATICALLY SUSPENDED GYRO

The application of electrostatically suspended gyro (ESG) to the stabilizing of platform is the first research project of employing this kind of gyro for navigation purposes in China. The platform is characterized by using the ESG pendulum as a horizontal sensitive element. Thus the nondisturbed Schuler condition in a single gyro can be realized by regulating the electrical parameters. The platform includes an ESG pendulum and its control circuits, platform control circuits, an ESG pendulum radial damping loop, and angle output devices against rolling and pitching. This paper describes the principles of the platform, its construction and error analysis, as well as the principle of the ESG pendulum and its control circuits, Measurements of platform accuracy in laboratory "and navigation tests are also given.
